A. Sherrod Blakely talked with Bradley and Doc after the game:

Bradley injures shoulder, uncertain for Game 4 - A. Sherrod Blakely - Comcast SportsNet

"It's really sore," Bradley told CSNNE.com after the game. "Every time I go to extend my arm, and it gets hit, it comes in and out." ...

"He's had that problem all year," said C's coach Doc Rivers. "Usually they're able to, like a lego, snap it back in. It wouldn't go back in."

Bradley will be undergo further evaluation on Saturday. He told CSNNE.com that he did not have any tests such as X-Rays or MRI's performed on it following Friday's win.

When asked whether he expected to play in Game 4 on Sunday, Bradley said, "Of course. As of now, yeah."

That sounds like a pretty standard disclocation. However, per Gary Washburn:

Source close to Avery Bradley tells Globe that AB suffered "stinger" type of injury, shoulder's not separated. Should play Sunday #celtics

Maybe it's semantics, but the way Doc and Bradley were talking about the injury, it sounded more like a dislocation / separation than a stinger (i.e., a pinched nerve). Maybe Washburn's source is talking about Bradley's current level of discomfort, or maybe Doc and Bradley were just using really strange descriptors for the original injury.

Whatever the case, it's great news that Bradley is planning on playing in Game 4. The kid is a trooper.
