With Jayson Tatum already back to playing one-on-one after tearing his right Achilles tendon in May, Boston Celtics head coach Joe Mazzulla was asked Wednesday when the team will begin conversations about the All-Star?s potential return. It?s all up to him, Mazzulla said after his team?s practice. At the end of the day, his health is the most important thing, his process is the most important thing. You trust him, trust the team that?s around him he?s got a great team and then you just kind of go from there. So it kind of just all starts (with) where him and his team think he?s at.
