Bradley came up limping early in the second quarter after planting awkwardly trying to apply defense on Mario Chalmers inside the halfcourt stripe. Bradley tried to walk off the injury, but the Celtics subbed him out quickly and he retreated to the locker room with trainer Ed Lacerte. The team announced he would not return and his status is uncertain moving forward with Boston closing a three-game road trip on Wednesday in Washington.
"It looks like he got it pretty good," Celtics coach Brad Stevens told reporters in Miami after the game. "He didn’t seem like he was walking great. If I had to guess, personally, I’d say [he won’t play Wednesday against the Wizards], but it would be a guess."
The Celtics already are thin at the guard position having traded away Jordan Crawford and MarShon Brooks last week, while also excusing Keith Bogans from the team. Recently acquired Jerryd Bayless sprained a toe in his left foot in Sunday's loss in Orlando. With Rajon Rondo on a slowly climbing minute restriction, Boston is leaning heavily on undrafted rookie Phil Pressey and will have to utilize wings Gerald Wallace and Chris Johnson (plucked from the D-League on a 10-day contract) to hold the fort at shooting guard.
Bradley had started all 43 games this season for Boston and entered Tuesday's visit to Miami averaging 14.8 points on 44.1 percent shooting.
The Celtics appeared set to sign D-League guard Vander Blue to a 10-day contract to add emergency guard depth.
