Brooklyn Nets point guard Deron Williams suffered a mild calf strain Friday night against the Cleveland Cavaliers, and has been listed as doubtful for Sunday's game against the Detroit Pistons after undergoing an MRI.

Williams appeared to injure himself throwing a pass to Kevin Garnett on Friday. There was no contact on the play.

Williams, the subject of various trade rumors, is averaging 15.6 points and 6.8 assists per game.
