Tennis champ Venus Williams has injured herself playing a celebrity doubles match with U.S. TV host Regis Philbin. The pair teamed up to take on Bahamian professional Mark Knowles and TV producer Michael Gelman on Tuesday (27Nov07). Williams and Kelly toasted their victory when the match aired on Wednesday's Live with Regis + Kelly. But the Grand Slam champion confessed she was left hobbling around after the game: "I pulled my hamstring. I got up this morning and hobble hobble. But I'm used to injuries. I just block them out."
