Danny Ainge had said he did not expect the Boston Celtics to engage in contract extension talks with Avery Bradley until next offseason, but the general manager says the two sides are now negotiating.

Ainge declined to comment beyond saying the Celtics are discussing a deal with Bradley's representatives.

Bradley will become a restricted free agent next summer if a deal is not reached by Oct. 31.

With Rajon Rondo injured, Bradley is expected to take a larger role on the Celtics this season.
