Every Celtics player took the court at the Auerbach Center on Tuesday for the team's first postseason practice, including Jaylen Brown.

Brown has battled a lingering knee issue — specifically a bone bruise with a posterior impingement, per the Celtics — since before the All-Star break. He sat out two straight games in mid-February, then missed 10 of Boston’s 27 contests after the break, never playing in more than four consecutively.
