Dwyane Wade is unsure if he will be able to compete in the London Olympics.

The Miami Heat guard told The Associated Press on Friday that he will soon have his ailing left knee examined, and acknowledges that surgery might be a possibility.

Wade played through pain in this year's playoffs, helping the Heat win the NBA Finals for the second time. Wade appeared in all 23 postseason games for Miami, averaging 22.8 points.

Wade says he isn't sure what the exact problem is with his knee, which was drained during the second round of the playoffs. He says he wants to play in the Olympics again, like he did when the Americans won bronze at Athens in 2004 and the "Redeem Team" took gold at Beijing in 2008.
