(AP) -- The Latest on the 2016 Summer Olympics in Rio de Janeiro (all times local):

11:20 a.m.

U.S swimmer Ryan Lochte has apologized for his behavior surrounding a late-night incident at a Rio de Janeiro gas station, saying he should have been more careful and candid about how he described what happened.

Lochte said in a lengthy post on Instagram Friday that he was apologizing for his role in taking the focus away from other Olympic athletes.

The 12-time gold medalist reiterated his view that a stranger pointed a gun at him and demanded money to let him leave.

But Lochte says he should have handled himself more responsibly.

Brazil police have said Lochte lied by saying he and three other swimmers were robbed. They vandalized a gas station bathroom and were confronted by security guards.

Toyota has become the second global sponsor of the new Olympic Channel.

The IOC says Toyota signed a four-year deal as a "founding partner" of the channel through the 2020 Tokyo Games. Terms were not disclosed.

Japanese tire manufacturer Bridgestone was announced earlier this week as the first commercial sponsor of the channel, which launches Sunday night after the closing ceremony of the Rio de Janeiro Olympics.

Toyota and Bridgestone are already among the IOC's global sponsors.

The digital channel will operate 24 hours a day, 365 days a year. It is designed to promote sports and athletes during the years between the Olympics.

Drama, yes, drama, in the men's 50-kilometer walk at the Rio Games, with world record holder Yohann Diniz keeling over after 35K, stricken by apparent stomach problems having built up a commanding early lead.

Officials helped the gritty high-school sports coach from France back to his feet. He doused his head with a bottle of water and was off again, but is struggling and has dropped back.

Evan Dunfee of Canada is now in a five-man lead group, along with reigning Olympic champion Jared Tallent of Australia and world champion Matej Toth from Slovakia, that is in medal-contention in the longest athletics event of the games.

Just when he was motoring, world record holder Yohann Diniz has run into problems in the men's 50-kilometer walk having built up an early lead.

With 20K to go, the high-school sports coach from France had been 1 minute, 28 seconds ahead of a slimmed-down chasing group of seven men, including the reigning Olympic champion, Jared Tallent of Australia, and world champion Matej Toth from Slovakia.

But he then pulled up complaining of stomach pain, just as the chasing group was picking up the pace to try to reel in the 38-year-old hunting an elusive Olympic medal in the longest athletics event of the games. Diniz rejoined the race after a brief pause but seems to be struggling. Evan Dunfee of Canada is now leading.

Burning sun and high temperatures are taking a toll on the 2-kilometer course looping back and forth along the Atlantic seafront west of Rio de Janeiro's famous Copacabana beach.

Sprays of water mist are in place on the route to cool the walkers, who are also dousing themselves with water from bottles and soaked sponges.

Malaysia's Lee Chong Wei has beaten two-time Olympic champion Lin Dan of China in Olympic Badminton, avenging his last two losses to Lin in the Olympic finals.

Both men are considered by many to be the best players of their era, and maybe of all time, and Friday's semifinal match was often thrilling.

Lee's reaction at the end -- falling to his knees, covering his face with his hands and putting his forehead on the court before leaping up in the air and pumping his fists -- made it seem more like a gold medal contest than the semifinals.

Lin jumped out to a commanding early lead in the first game of the best-of-three match, and fended off a Lee rally to win 21-15. Lee, his nerves settled, came out fast in the second game and won 21-11. The deciding game was much closer, with the lead swinging back and forth. Lee stretched out a small lead toward the end and was on the brink of winning, but Lin charged back, fighting off several match points to tie the game at 20. Lin then pulled away to win 22-20.

Lee, who served an eight month doping ban, is looking for an Olympic championship to ease the heartbreak of the two previous final-match losses to Lin.

Standing in the way will be two young powers: China's Chen Long plays Viktor Axelsen of Denmark in the other semifinal match Friday.

Later Friday the women's singles gold medal match will be decided, as Spain's Carolina Marin, the world No. 1, plays surprise finalist P.V. Sindhu of India.

Malaysia and China will also play in the men's doubles gold medal match.

American Steven Lopez is through to the quarterfinals of the taekwondo competition at the Rio de Janeiro Olympics after winning his first-round fight against Albert Gaun of Russia.

The match started tentatively, but Lopez landed a spinning roundhouse kick during the second round that gave him a definitive lead. Lopez eventually won the fight by a score of 7 to 4.

Lopez said he was very happy to make it through the first fight of the day, which he said is usually the toughest one of the day because of nerves. Lopez is the first taekwondo athlete to compete in five Olympic Games.

"I'm just blessed with this opportunity to be able to go out there and perform my best. And my best was enough to win the first match," he said. Lopez will fight his next match on Friday afternoon when he faces Lutalo Muhammad of Great Britain.

Yohann Diniz, the world record holder from France, has undulated to an early lead in the men's 50-kilometer walk.

Pushing the pace in his chase for a first Olympic medal, Diniz was closely scrutinized by walking judges and was quickly shown a yellow card for suspect technique. Diniz has a history of disqualifications in major races, including the 2012 London Games and 2011 and 2005 World Championships.

By the 10-kilometer mark, Diniz had built a lead of 30 seconds over a nine-man chasing group that included the reigning Olympic champion, Jared Tallent of Australia, and world champion Matej Toth from Slovakia.

Diniz, a high school sports coach, walked the first 10 kilometers in 44 minutes, 18 seconds -- which would be a good pace for an amateur fun-runner. By the 15-kilometer mark, he was already starting to lap back markers.

On Day 14 of the Rio Games, Usain Bolt says he will be running in his last Olympic race.

The astonishing Jamaican sprinter and teammates are the favorites in the men's 4x100 relay. Seven gold medals are up for grabs Friday in track and field, out of 22 overall in Rio. The American women seek a win in the 4x100 relay and U.S. pole vaulter Jenn Suhr tries to defend her title.

In soccer, Sweden takes on Germany in the women's gold-medal match.

The U.S. women face Italy in water polo while the Dutch women seek an unprecedented third straight gold against Britain in field hockey.

Mariana Pajon of Colombia tries to defend her gold medal in BMX cycling while the BMX men seek medals in a race blown wide open after crashes in qualifying.

In semifinals, the U.S. men play Italy in volleyball and Spain in basketball.

Usain Bolt says this will be his final Olympic race.

(Michael Phelps said that too once, but that's a whole 'nuther story.)

The astonishing sprinter is back on the track Friday, looking to add to his medal stash as part of the Jamaican team in the 4x100 relay. Bolt and Jamaica won the event at the Beijing and London Olympics, where the team set the world and Olympic records.

So far, there's only one opponent that can really beat Bolt -- and that's time.

Bolt romped in the 200 meters Thursday night, but finished in 19.78 seconds, .59 short of his own world record. Still, that gave him Olympic gold medal No. 8 and a third straight 200 title to go with the same trifecta in the 100 meters.

As for his Rio Olympic goals, Bolt said immortality was the main one.

"What else can I do to the world to prove I am the greatest? I'm trying to be one of the greatest. Be among Ali and Pele," Bolt said.

The lawyer for U.S. Olympic swimmer James Feigen says he will pay about $10,800 Friday and then leave Brazil following the robbery scandal involving the U.S. swim team.

Attorney Breno Melaragno says early Friday that, under an agreement reached with a Brazilian judge, Feigen will donate 35,000 Brazilian reals to an "institution" and depart.

Melaragno did not specify where the money will go, but the term "institution" can be taken to mean charity. The lawyer said under Brazilian law, a donation can be made to avoid criminal prosecution for minor offenses, but did not say what charge was being contemplated against Feigen.

Feigen's teammates Gunnar Bentz and Jack Conger left Brazil on Thursday night after giving testimony to police.

Police say U.S. swimmer Ryan Lochte and the three others had not been held at gunpoint, as Lochte initially claimed. Instead, Brazilian police say the U.S. athletes were intoxicated, vandalized a bathroom, then were questioned by armed guards before they paid for the damage and left.

Spain was always going to be in the way of the U.S. men's basketball team at the Rio Olympics -- whether it was playing for the gold medal, as they had in the last two Olympics, or just for the chance to get into the gold medal round.

Spain gets another chance Friday to knock off the U.S. men after being oh-so-close in the 2012 and 2008 Olympics.

"It would mean everything for us," says Spanish point guard Ricky Rubio. "I remember watching Argentina beat the U.S. in 2004, and I think maybe the same story that Argentina wrote with the 'Gold Generation,' we can write, too."

In the other semifinal, Australia plays Serbia. Both teams came close in their games against the U.S. as the favorites have shown some vulnerability in Rio.

Germany had better hope that the women's Olympic soccer final Friday against Sweden doesn't come down to penalty kicks.

The Swedish team is getting a reputation as a giant-killer in Rio. While many figured that the World Cup champion U.S. team would be cruising to its fourth straight Olympic gold, Sweden beat them on penalty kicks.

With the U.S. out, many thought host Brazil and its star Marta would surely be playing for gold -- but Sweden knocked them off on penalty kicks.

Neither Sweden nor Germany have never played before in a women's Olympic soccer final but their coaches have known each other for decades. Germany's Silvia Neid, who is stepping aside after this Olympic final, and Sweden coach Pia Sundhage were both in the first women's Olympic soccer tournament in 1996.

Canada and Brazil face off earlier Friday for the bronze medal.

Brazilians adore the beach and the water -- so nothing could be better for the Olympic host than picking up its latest two golds at those venues.

The men's volleyball team of Alison and Bruno set off a boisterous celebration in the rain on Rio's Copacabana Beach when they won, and had to hold back tears as compatriots belted out the national anthem next to the crashing surf.

"In front of our people. In the best spot for this sport," Bruno said. "This is a magical feeling."

After snatching away the gold with a dramatic finish in the women's 49erFX, sailors Martine Grael and Kahena Kunze hugged, then flipped backward off their boat into Guanabara Bay. Family and friends jumped into the surf to celebrate, then carried the sailors' boat up to the beach with the women still standing in it.

"It's actually how I hoped I could be taken out of the water," Grael said.
