WALTHAM, Mass. — Boston Celtics forward Kevin Garnett is nursing a right foot injury that has kept him out of practice.

The Celtics and Cleveland Cavaliers are tied 1-1 in their best-of-seven Eastern Conference semifinal series. Game 3 isn't until Friday night, and coach Doc Rivers says he expects Garnett to play.

Garnett showed up for practice at the team's workout facility Wednesday but wasn't able to fully participate, so Rivers told him to rest his foot. Rivers said Garnett sprained his ankle, but Celtics spokesman Jeff Twiss said it was a mild mid-foot strain.

Center Kendrick Perkins also missed practice. He hyperextended his right knee in the shootaround before Monday night's game, but played anyway.

Garnett was injured late in the 104-86 win in Cleveland.
