Miami Heat star Dwyane Wade is unsure when he will return from a strained right hamstring, leaving him in doubt for the NBA All-Star game at Madison square Garden in New York on February 15.

Wade, who was named as a reserve in the Eastern Conference on Thursday, suffered the injury during Tuesday's 109-102 loss to the Milwaukee Bucks.

The 33-year-old - averaging 21.4 points per game this season - left the game in the third quarter and did not return at American Airlines Arena.

Wade has no idea when he will return to the court and is now in doubt for the All-Star clash in less than two weeks.

"I won't be seeing y'all for a little while, so take a good look at this face," Wade told reporters. "You can't put a time on it. You can't look at the hamstring and say you're going to be out this amount of games.

"Like many muscle strains, you've got to go day by day. "Where this thing has me is frustrated and where I stand I have no idea. It's just the second day of a pulled hamstring."
