Jakob Poeltl Questionable for Saturday's Game vs. Celtics with Back Injury

Toronto Raptors center Jakob Poeltl (back) is questionable for Saturday's game against the Boston Celtics as the team continues to monitor his lower-back injury. If Poeltl is unable to play, Sandro Mamukelashvili would likely step into the starting center role and could see a significant increase in fantasy value.
