Jayson Tatum, the Celtics star, is expected to play in the crucial Game 7 of the series against the 76ers, after being treated for a leg injury during the team's 106-93 defeat. Tatum had to leave the game early in the third quarter and did not re-enter in the fourth quarter, prompting head coach Joe Mazzulla to send in a lineup of bench players with over 10 minutes remaining. He said he was dealing with stiffness in his left leg, not the right leg that was surgically repaired after he ruptured his Achilles in May.
