On the challenging course sitting next to the London Velodrome, American rider Brooke Crain crashed in the home stretch in a section made of a succession of small jumps. She managed to get back on her bike to cross the finish line but officially was listed as not finishing. If she's able to continue, she would be given the 16th and final seed.
Latvian rider Edzus Treimanis also went down on the track at the same spot, falling face first.
SAILING: The U.S. was shut out of Olympic sailing medals for the first time since 1936 when women's match racing skipper Anna Tunnicliffe was beaten in the quarterfinals by Finland.
BOXING: Middleweight Claressa Shields dominated Kazakhstan's Marina Volnova in the semifinals of the first Olympic women's tournament, earning a spot in the title bout against Russia's Nadezda Torlopova.
After pounding away at the slower Volnova for most of the 29-15 fight, the 17-year-old Shields pounded her taped right fist against her own left shoulder and screamed with joy.
Shields is the last American boxer left in London after flyweight Marlen Esparza lost 10-8 to Chinese world champion Ren Cancan an hour earlier. Ren will fight Britain's Nicola Adams for the flyweight title.
WATER POLO: The U.S. men's team was eliminated with an 8-2 quarterfinal loss to unbeaten Croatia.
The Croats jumped to a 5-0 lead by halftime with ferocious defense on one end of the pool and efficient shooting on the other. The Americans clawed back to 5-2 halfway through the third quarter, but Miho Boskovic responded for Croatia with his second goal before Sandro Sukno added another with four seconds left in the period.
CANOE SPRINT: Germany's 500-meter K-4 team lost an Olympic final for the first time since the 1992 Barcelona Games, falling to a Hungarian quartet looking to spring an upset after second-place finishes at the last three Summer Games.
It also meant Hungary finished the first day of finals at the canoe sprint regatta with the upper hand over Germany in their head-to-head competition in the event's medals table.
WRESTLING — FREESTYLE: Japan won a pair of women's freestyle wrestling events, with Kaori Icho taking the 63-kilogram division and Hitomi Obara finishing on top of the 48-kg category.
DIVING: China's Chen Ruolin led the women's 10-meter platform preliminaries, with the teenager trying to add a gold medal in the individual event to the one she won in platform synchro.
