Toronto, ON (SportsNetwork.com) - Toronto Raptors guard DeMar DeRozan suffered a left groin strain in the third quarter of Friday's game against the Dallas Mavericks.

He dribbled past Dirk Nowitzki on the right side of the lane, but DeRozan's left leg slipped, causing him to fall to the floor. DeRozan was writhing in pain with 8:23 remaining in the period. He eventually got to his feet and walked off the court gingerly. The Raptors said DeRozan would not return.

Before leaving the contest, DeRozan was held scoreless on 0-for-8 shooting from the field. He entered Friday leading the Raptors with 20.7 points a game.
