BOSTON -- In a seismic development, Boston Celtics superstar Jayson Tatum was ruled out of Game 7 of the Eastern Conference quarterfinals against the Philadelphia 76ers with left knee stiffness.
The designation comes just under two hours before tipoff of the conclusion of the latest installment of one of the league's oldest rivalries.
"He just came in today with knee discomfort," Celtics coach Joe Mazzulla said during his pregame media availability a few minutes after Tatum was ruled out. "And we decided, the medical staff and myself, that he would not play."
Mazzulla, who added Tatum had discomfort behind his knee and that he was day-to-day, declined to say who would be starting in Tatum's place.
