Jonas Valanciunas is expected to miss four to six weeks while he recovers from a broken ring finger on his right hand.
"He saw a hand specialist," Raptors coach Dwane Casey said. "But he doesn't have to have surgery and that's the main thing, the positive out of the whole thing. It's unfortunate because again he was getting in a good little rhythm, getting some rest, not playing as many minutes, but then this setback."
Aaron Gray and Amir Johnson are expected to fill the void in Valanciunas' absence.
Valanciunas was averaging 7.8 points and 5.2 rebounds.
