Richard Jefferson suffered a dislocated right thumb during a workout at the Spurs' practice facility on Tuesday.

Jefferson's X-rays were negative, according to the Spurs.

The small forward will be examined again next week and a determination on when he can resume basketball activities will be reached then.

Jefferson was acquired by San Antonio via a pre-draft trade with the Bucks that sent Bruce Bowen, Kurt Thomas and Fabricio Oberto to Milwaukee.
