Today's BMX races were rained out and put over to Friday. The delay might give Kyle Bennett of the U.S. time to rest his dislocated shoulder.
Rain is forecast for much of the day today, so there is a chance that Friday will be a no-go, too.

Officials also moved Friday's women's mountain bike race to Saturday morning because of the rain on the course. The men's mountain bike event is still scheduled for Saturday afternoon.
