The Brooklyn Nets announced Thursday afternoon that point guard Deron Williams is out indefinitely due to a fracture of the cartilage portion of the left 12th rib.

An MRI revealed the injury, and the Nets say there’s no timetable for Williams’ return to action.

From the press release:

Statement from Nets Medical Director Dr. Riley Williams III

 

“Deron reported some soreness above this area over the weekend and as a result underwent imaging studies on Monday, which were negative. Yesterday during the game he reported a new onset of symptoms below the prior area of soreness. New imaging studies done today demonstrated the fracture. There is no timetable for his return. He will be re-assessed in one week.”

 

Williams has appeared in 32 games (25 starts) this season, averaging 13.9 points, 6.3 assists and 3.0 rebounds in 31.3 minutes per game. He ranks 14th in the NBA in assists per game.
