Celtics' Bradley out at least a week with ankle injury

The ankle sprain injury suffered by Avery Bradley on Tuesday night will keep him out of tonight's lineup for the Celtics and possibly longer.

Celtics president of basketball operations Danny Ainge told that Bradley was "definitely" out for tonight's game. Bradley's absence beyond that, Ainge said, has yet to be determined.

A league source told CSNNE.com that Bradley will likely miss "at least a week, maybe more" with the injury.
