DALLAS -- An MRI revealed that Mavericks small forward Chandler Parsons suffered a sprain and bone bruise to his left ankle, a source said Saturday.

Parsons is doubtful to play Sunday against the Charlotte Hornets, the first of three games in four days for the Mavs.

Parsons, the Mavs' prized summer free agent addition, rolled the ankle when he came down awkwardly after a rebound in a win over the Houston Rockets, his former team.

Parsons is averaging 15.4 points, 4.8 rebounds and 2.4 assists this season.
