Chicago Bulls point guard Derrick Rose had to be helped off the court after suffering an apparent left knee injury in Game 1 of the Eastern Conference quarterfinals against the Philadelphia 76ers on Saturday.

Rose, who missed 27 games during the regular season with various injuries, went down with 1:10 remaining after driving to a jump-stop in the lane and throwing a pass out to the right.

He crawled slowly to the floor and was lying on his back, grasping at his knee, for several minutes before he was helped off.
