Nelson hurt, out three months


Diane Nelson, who was thrown from her mount, Sonn D'Oro, while leading on the far turn in Thursday's first race at Belmont, sustained two fractures in the bones connecting her left leg to her ankle. She was scheduled for surgery at the Hospital for Special Surgery in Manhattan on Saturday and is expected to be out of action for about three months.

Javier Castellano, also unseated in the spill, took off his mounts on Friday but was scheduled to ride over the weekend.
