RIO DE JANEIRO (AP) -- Simone Biles is no longer Rio de Janeiro's juggernaut. A mistake on the balance beam Monday prevented the American gymnastics star from a record-tying fourth gold at the Rio de Janeiro Games.
The blunder allowed Sanne Wevers of the Netherlands to take the gold medal and Laurie Hernandez of the U.S. to slip past her for the silver. It also ended Biles' bid to become the first female gymnast to win five golds in a single Olympics.
Later Monday, world champion Allyson Felix goes for her fifth Olympic gold medal when she runs in the women's 400-meter final as Day 10 of the Rio Olympics features competition in track and field, boxing, cycling, marathon swimming, wrestling and more.
Once again, however, the Rio Games were dogged by bad news:
--The German Olympic team said canoe slalom coach Stefan Henze has died from injuries sustained in a car crash last week.
--The Egyptian judo athlete who refused to shake his Israeli opponent's hand after losing a first-round heavyweight fight was sent home. The IOC called Islam El Shehaby's conduct following his loss to Or Sasson "contrary to the rules of fair play and against the spirit of friendship embodied in the Olympic values."
--The Olympic Broadcasting Service said seven bystanders sustained minor injuries when a television camera it operates plummeted about 30 feet in the Olympic park. At least one woman was taken to a hospital.
--Whipping winds sent smoke and ash from a nearby wildfire billowing over the field hockey stadium in Deodoro Monday afternoon. Germany and the United States had finished playing a women's field hockey quarterfinal about an hour before the smoke became noticeable.
--Usain Bolt, the marquee name of these games along with Michael Phelps, said that a tight schedule slowed down the sprinters in the 100 meters Sunday.
Bolt said that's why he had a lumbering start when he won his third consecutive gold in the event, defending his title as the world's fastest man. For TV purposes, there was only one hour between the semifinal and final rounds.
"I don't know who decided that," Bolt said. "It was really stupid. So, that's why the race was slow."
Already a three-time gold medalist (all-around, team and vault) when she walked onto the floor on Monday, Biles was a favorite on beam as the reigning world champion. She topped qualifying last week and had just completed the most difficult part of her routine -- a tumbling pass that stretches the length of the 4-inch wide slab of wood -- when she missed the landing following her punch front flip.
Other highlights from Day 10:
LONE RUSSIAN : The lone Russian track and field athlete at the Olympics has won her appeal to compete in Rio. The Court of Arbitration for Sport ruled early Monday that Darya Klishina is eligible to take part in Tuesday's long jump qualifying because she has been based outside of Russia for the last three years and has been subjected to regular drug testing.
DUCKING OUT : The Oregon Ducks are taking a page from the New England Patriots, who halted practice last week to watch Nate Ebner compete in Olympic rugby sevens. Devon Allen will make his Olympic debut later Monday when he runs in the opening heats of the 110-meter hurdles. The Ducks plan to take a break from practice to watch the wide receiver run his heat.
GOLF AGAIN : Brazilian native Miriam Nagl has been chosen to hit the opening tee shot Wednesday for women's golf, at the Olympics for the first time since 1900 in France. On Sunday, Justin Rose won the first golfing gold medal since 1904 in St. Louis when he beat Henrik Stenson by two strokes on the Olympic course.
