Tennis: Ankle blow 'crushing' for Roddick

Andy Roddick added to the ever-growing list of injured casualties at the Australian Open as he tumbled out of his second round encounter in Melbourne.

The American 13th seed fell on an already injured right ankle as he ran wide for a forehand, tried to use his right foot to stop, and fell awkwardly. He got up slowly and continued playing, but couldn't hit effectively.
