Jayson Tatum will not play in the Celtics' upcoming game against the Thunder due to a right Achilles injury. This will be the first game he has missed since returning from injury. Despite averaging 19.7 points and shooting 39.3 percent from the field, Tatum's performance has been inconsistent. He has played exactly 27 minutes in all three games since his return. The Thunder, which has the best overall record in the NBA, is also the defending NBA champion. Payton Pritchard will return for the game against OKC.
