The tough times for America's Olympic BMX team started before the Games were even underway: star Arielle Martin had to drop out after a devastating crash on the team's last day of training before leaving for London. Martin's replacement, Brooke Crain, didn't fare much better during today's seeding run at the BMX course north of London's Olympic Park.

Crain crashed and burned in the last straight of her run, taking more than a minute to get up though she did manage to finish the course. The AP reports it's unclear if Crain will be able to recover in time for Thursday's semifinal. Crain's already dealing with the effects of a broken arm suffered at the World Championships.
