The Miami Dolphins offensive line woes were to blame in part for Sunday's injury to starting quarterback Matt Moore, who suffered a head injury, according to the South Florida Sun-Sentinel.

If Moore has a concussion, it mean that the Dolphins will have to turn to J.P. Losman, a one-time starting quarterback whom the Bills gave up on a few years back.

If so, Losman, signed after Sage Rosenfels was placed on the non-football injury list, would be the third quarterback to start for the Dolphins this year, after Chad Henne and Moore.
