The Spurs received another setback Wednesday when they learned starting center Francisco Elson has a small tear in his right rotator cuff and will be out about two weeks.

Elson was injured in the first half of Tuesday's loss to Milwaukee. Team officials said he suffered an impingement to his shoulder, which is caused by the shoulder blade pressuring the rotator cuff when the arm is raised.

Fabricio Oberto is expected to start while Elson is out. Spurs coach Gregg Popovich said forward Eric Williams and center Jackie Butler could see more time depending on matchups.
