The Celtics look to play without him on Saturday night as they plan to get past the Philadelphia 76ers in a pivotal Game 7.
"It's disappointing," said head coach Doc Rivers. "Obviously when a player goes down, that's disappointing, especially on what Avery has given us this year. His growth this year has been terrific, and it's been great, and he's become a very valuable piece to our basketball team."
ESPN Boston reports that Bradley will likely go under a four-month rehab.
Bradley made a nice rebound in his second season, filling in well at the starting shooting guard position for Ray Allen. It's a big blow to see him out.
"Avery's a big blow, yeah, there's no doubt," Rivers said. "If I'm the other guys on any other team, and the fact that I don't have to play against Avery Bradley, I would sleep a little better. No one wants to play against Avery. Our guys don't want to play against him in practice. He's a pain in the (butt) defensively. That's what he does."
If the Celtics win Game 7, they'll face the Miami Heat in the Eastern Conference Finals.
