FLORHAM PARK, N.J. — New York Jets quarterback Mark Sanchez says he is unable to run on his surgically repaired left knee six weeks after the procedure, but will "definitely" be ready to take the field when training camp begins in July.

Sanchez had surgery to repair the patella ligament on Feb. 17, and says Thursday that he's working on gaining more leg strength and range of motion. He also says doctors are pleased with his recovery and they have been "cautiously aggressive" with the rehabilitation.

Sanchez, who led New York to the AFC title game as a rookie, dislocated the kneecap during fall practice before his junior season at Southern California. He aggravated the injury against Carolina last Nov. 29.
