Tatum isn't the only Celtics star that underwent surgery early this offseason. Brown had a successful arthroscopic procedure on his right knee and is already back in the facility working out, per Stevens. "We said be ready for training camp and I think he'll probably be going full well ahead of that," Stevens said.

Boston Celtics star forward Jayson Tatum is just over a month removed from undergoing surgery on his torn Achilles, and even though he's moving in the right direction, the team won't rush his return to the court.

Jayson Tatum and Jaylen Brown are rehabbing their respective injuries this summer as they've spent a lot of time at the Auerbach Center facilities.
