RIO DE JANEIRO -- Day 10 of the Rio Games features medal action in track and field, boxing, cycling, marathon swimming, wrestling and more. Here are some things to watch (all times local):TRACK AND FIELDWorld champion Allyson Felix will be going for her fifth career Olympic gold medal when she runs in the womens 400-meter final. Felix won her heat in the semifinals on Sunday in a season-best 49.67 seconds, the fastest time in the field. She is running only in the 400 after missing a chance to defend her Olympic 200-meter title by failing to make the U.S. team. The final is scheduled for 10:45 p.m.Devon Allen, the Oregon football player who is competing in Rio, will make his Olympic debut when he runs in the opening heats of the 110-meter hurdles. Allen is the first collegian to win the 110-meter hurdles at the Olympic Trials since Marylands Renaldo Nehemiah in 1980. The Ducks football team plans to take a break from practice to watch Allen, a receiver on the team, run in his heat, which is scheduled to start at 9:04 p.m.There are also medals up for grabs in mens pole vault and mens 800 meters.BEACH VOLLEYBALLThe U.S. mens beach volleyball team of Phil Dalhausser and Nick Lucena play their quarterfinal match on Monday (4 p.m.) against the defending world champions from Brazil, Alison and Bruno. Its the toughest test yet for Dalhausser, the 2008 gold medalist, and his rookie partner.BOXINGA thoroughly entertaining Olympic heavyweight tournament concludes with the gold-medal bout between Russian world champion Evgeny Tishchenko and Kazakhstans fearsome Vassilliy Levit. The winner joins an elite lineage of Olympic champions at the glamour weight, including George Foreman, Ray Mercer and three-time Cuban champs Felix Savon and Teofilo Stevenson. Levit beat Savons nephew, Erislandy, to reach the final. The main event of a 19-fight card is at 7:15 p.m.GYMNASTICSSimone Biles will try to make it 4 for 4 when the Olympic all-around champion makes a bid for another gold medal during the balance beam finals.The 19-year-old already has three golds from the team final, the all-around and the vault, which she won on Sunday. Her three golds are the most by an American female gymnast during one Olympics. Biles is the world champion on beam and posted the highest score during qualifying when she put up a 15.633. Biles biggest challenge will likely come from teammate Laurie Hernandez, who edged Biles during the Olympic Trials last month and scored 15.366 during qualifying.The men will hand out individual medals in vault and still rings.MENS BASKETBALLComing off a thrilling double-overtime win against rival Brazil, Argentina wraps up pool play against Spain.

Spain and Argentina tip off at 7 p.m.WRESTLINGCuban heavyweight Mijian Lopez will wrestle for his third Olympic title Monday at the Rio Games. But Lopez will likely have to get through Turkish strongman Riza Kayaalp to win gold. Kayaalp stunned Lopez in the 2015 world championships, and a second win over the Cuban would signify a shift in dominance between these long-time rivals.MARATHON SWIMMINGWith concerns about the quality of the water plaguing the Rio Games, the womens 10-kilometer marathon will be held at 9 a.m. The women will be swimming a course just off of Copacabana Beach, competing in an event that started in Beijing in 2008. It takes most of the swimmers about two hours to complete the 6.2-mile course, and adding to the difficulty this year is the heavily polluted water of the Atlantic Ocean just off of the coast. American Haley Anderson won silver in London, narrowly missing out on the gold.TRACK CYCLINGMark Cavendish , the winner of 30 stages in the Tour de France, tries to capture the Olympic medal that has long eluded him when he returns to the Rio velodrome for the omnium.

It starts at 5:23 p.m.WATER POLOAfter starting their tournament play outdoors, the women move inside for quarterfinal action.

PORT-AU-PRINCE, Haiti -- Its been nearly 90 years since Haiti earned a medal at the Olympic Games. But swimmer Frantz Mike Itelord Dorsainvil is aiming to break that dry spell.The lanky 25-year-old swimmer who only began to swim competitively six years ago is arguably the most unlikely Olympian on Haitis small team. But he doesnt lack for confidence.I will be giving all my effort to make sure I bring back a medal for my homeland, Dorsainvil said after a recent day of training.The swimmer, who has never lived abroad -- unlike many athletes who typically represent the impoverished Caribbean country -- trains in an 18-meter long pool. An Olympic-sized pool is 50 meters.I have to do six laps just to make 100 meters. I go back and forth, back and forth, he laughed during a phone interview from the pool in Carrefour on the outskirts of the capital Port-au-Prince.ddddddddddddSwimming barely exists as a sport in Haiti, where there are few pools. Many Haitians, even some who fish for a living, never learn how to swim.Dorsainvil is hoping to change all that.He says hes hopeful that the sport will take off in his Caribbean homeland if he and his teammate, 19-year-old Haitian-American Naomy GrandPierre, are able to win a medal. GrandPierre is a student at the University of Chicago and will be Haitis first Olympic female swimmer.I hope we can help make swimming popular here. Its disappointing that so many Haitian people are not able to swim, Dorsainvil said. ' ' '
