Semifinals in the 200-meters are set for Wednesday the final for Thursday. Bolt is looking to win this eighth Olympic gold medal.

The Irish boxer flipped out when he lost a unanimous decision in a bantamweight bout that cost him a shot at fighting for a medal. The 24-year-old Conlan stripped off his vest, stormed around the ring made an obscene gesture toward the judges. He gave two thumbs down in the ring and gestured toward booing fans.
Conlan, a bronze medalist in the 2012 London Games, took his time leaving the ring and didn't put his vest on when he talked to reporters.
He even grabbed a microphone at one point in the mixed zone to loudly state his case he was robbed of his Olympic dream.

Conlan used profanity in a tirade directed at the International Boxing Association (AIBA) and said he would never fight in an amateur bout again.

The Algerian made sure he won his heat in 3 minutes 46.82 seconds, almost 20 seconds slower than his personal best. And almost 8 seconds behind the qualifying time of Kenyan favorite Asbel Kiprop.
Still, silver around his neck boosted his confidence for a second medal. "This gives me great hope for the 1,500. It's like a bonus," he said. "It is the first time to do 800 and 1500 in a big championship."

The 24-year-old Ethiopian, the world champion in the 5,000, surged away from the pack with seven laps to go in heat 2 and led all qualifiers in 15 minutes, 4.35 seconds on Tuesday — 13 seconds clear of countrywoman Senbere Tefere, the world championship silver medalist.
Vivian Cheruiyot of Kenya, the Olympic silver medalist in the 5,000 and two-time world champion, was next in 15:17.74.
With the first five in each heat and the next five fastest advancing to Friday's final, there was plenty of jostling for positions.
Two of the casualties were American Abbey D'Agnostino and Nikki Hamblin of New Zealand, who tangled and both ended up on the track in the second heat. D'Agnostino got up to help Hamblin, who was sprawling on the ground. Then as D'Agnostino hobbled on what appeared to be a right ankle injury, Hamblin tried to help her continue.
In the end, Hamblin finished in 29th place, one ahead of D'Agostino. The pair embraced at the finish, before D'Agostino was taken from the track in a wheelchair.

The crowd at Lagoa stadium roared for Queiroz, who was chasing Brazil's first gold in flatwater canoeing. The Brazilian's nickname is "Sem Rim," or missing kidney, because he lost one kidney after falling from a tree at age 10.
Queiroz will also race in the men's 200-meter sprint and the 1,000-meter doubles.
1:20 p.m.
On Day 11 of the Rio Olympics, Simone Biles is seeking a fourth Olympic gold, one of 28 to be handed out.
Her challenge Tuesday comes in the floor exercise, where the American gymnast will try to fend off teammate Aly Raisma. Biles has already earned three golds — and a bronze Monday night when she wobbled during the balance beam final.

Semifinals are taking place in women's soccer and in men's and women's beach volleyball; knockout play begins in women's basketball, with the U.S. facing Japan; and the men are swimming in the open ocean off Copacabana beach.
12:30 p.m.
Brazilians love the beach — and they are really loving the beach volleyball competition at the Rio Olympics.

10:40 a.m.
Not too many athletes can be slammed into the hard track of the Olympic velodrome at a high speed, bike and body sprawling in all directions, and get up and finish a 160-lap course to win gold.
But Elia Viviani of Italy is not just any athlete.
After the crash Monday night, Viviani realized he wasn't hurt and he was still leading the final race in the omnium - the six-event, two day men's competition.
So Viviani hauled himself back onto his bike and held off stiff challenges from British cycling star Mark Cavendish and reigning gold medalist Lasse Norman Hansen of Denmark.
"It's a bike race," Viviani said of the crash, caused when Cavendish collided with Korean rider Park Sang-hoon. "We're on a track, no brakes. When one guy changes directions in front of you and someone else is not ready to change directions, you crash."
9:55 a.m.
He's feeling good. And that's never good for his competition.
The heats for Usain Bolt's favorite race - the 200 meters - are beginning Tuesday at the Rio Olympics and the Jamaican sprinter is remarkably relaxed.
"I'm always confident going into the 200 meters," said Bolt, who surged past Justin Gatlin to win the 100 meters on Sunday, his seventh Olympic gold.
Also Tuesday, American Christian Taylor will try to defend his triple jump title, while Jamaica's Omar McLeod and American Devon Allen, the University of Oregon football/track standout, are among those seeking gold in the men's 110-meter hurdles.
Medals also will be awarded in the women's discus, the women's 1500 meters and the men's high jump.

On most days at the Summer Olympics, the talk focuses on times and medals and world records.
On Monday in Rio de Janeiro, it was all about the weather.
High winds and driving rain flipped sailboats over like tub toys, caused throwers to foul or release their discus early, threw pole vaulters off their stride and made running on parts of the Olympic track like splashing through puddles.
The 110-meter hurdles heats were hard hit, prompting organizers to run a special race later in the night for those who did not quality when the weather was the worst.
"It's atrocious. It's hard to compete in weather like this," said Jamaican hurdler Omar McLeod, who won the first heat amid heavy rain. "The water is beaming down in your face and your eyes and it's real hard."
Some sailing races were canceled and the boats raced to get back to shore safely.
At the Olympic Stadium, someone had some fun: "Singin' in the rain" was blaring on loudspeakers.
8:50 a.m.
The Russian runner who blew the whistle on Russia's doping scandal fears for her safety and has switched residences after hackers breached a database that records her whereabouts.
Yulia Stepanova and her husband, Vitaly, spoke up about a state-run doping system in Russia that led to the ouster of the country's athletes from the Rio Olympic track meet.
Recently, their email was hacked and the password stolen for Stepanova's account on a database controlled by the World Anti-Doping Agency. Like hundreds of athletes, Stepanova accesses the WADA system to enter her whereabouts, so doping-control officers can find her if she's selected for out-of-competition testing. The database also contains personal contact information, such as phone numbers and addresses.
Stepanova told reporters Monday "if something happens to us, you should know it's not an accident ... we are trying to take every measure possible to keep ourselves safe."

Brazilian female athletes are shining at the Rio Olympics - and people here are paying attention, some for the first time.
In a country where men's soccer is king, Brazilian women have found it difficult to find their place in sports because of the lack of athletic programs, funding and what they call unfair marketing decisions that promote men.
But now each victory of Brazil women's soccer team is being savored. And when Rafaela Silva won gold in women's judo - Brazil's first gold medal of this Olympics - major newspapers splashed her photo on their front pages.
The country's most famous female soccer player, Marta, told reporters "all the love we are getting during the Olympics, we hope that it doesn't go away ... with that much-needed support, women's soccer can grow."
Her team faces Sweden in Tuesday's semifinal.
