What to watch at the Rio Games on Monday

RIO DE JANEIRO (AP) 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 FIELD

World champion Allyson Felix will be going for her fifth career Olympic gold medal when she runs in the women's 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 Maryland's 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 men's pole vault and men's 800 meters.

BEACH VOLLEYBALL

The U.S. men's 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. It's the toughest test yet for Dalhausser, the 2008 gold medalist, and his rookie partner.

BOXING

A thoroughly entertaining Olympic heavyweight tournament concludes with the gold-medal bout between Russian world champion Evgeny Tishchenko and Kazakhstan's 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 Savon's nephew, Erislandy, to reach the final. The main event of a 19-fight card is at 7:15 p.m.

GYMNASTICS

Simone 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.

MEN'S BASKETBALL

Coming off a thrilling double-overtime win against rival Brazil, Argentina wraps up pool play against Spain. The Argentinians are 3-1 and have their sights set on their third Olympic medal.

Spain, the two-time defending silver medalists, led by center Pau Gasol, drubbed Lithuania by 50 in their previous game . The Spaniards will earn a spot in the quarterfinals with a win or if Brazil loses to Nigeria in Monday's first game in Group B. Spain and Argentina tip off at 7 p.m.

WRESTLING

Cuban 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 SWIMMING

With concerns about the quality of the water plaguing the Rio Games, the women's 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 CYCLING

Mark 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. Reigning gold medalist Lasse Norman Hansen of Denmark leads the six-discipline event at the midway point, but the British star is within striking distance. It starts at 5:23 p.m.

WATER POLO

After starting their tournament play outdoors, the women move inside for quarterfinal action. The Americans play Brazil at 2:10 p.m. They have started defense of their Olympic title by going 3-0 in group play . Australia plays Hungary, Russia plays Spain and Italy faces China in the other games.

WEIGHTLIFTING

The men's 105-kilogram class opened up in June when the world record holder Ilya Ilyin of Kazakhstan was suspended for failing retests of his drug test samples from the 2008 and 2012 Olympics. With Ilyin out of the picture, gold medal contenders include fellow Kazakh Alexander Zaichikov, who is the reigning world champion, Uzbekistan's Ruslan Nurudinov and China's Yang Zhe. The medal round begins at 7 p.m.
