An MRI on Sunday showed that Dallas Cowboys starting strong safety Gerald Sensabaugh suffered a subluxation in his left shoulder. He is expected to be sidelined three to four weeks, which could force him to miss the regular-season opener at the Washington Redskins on Sept. 12. Kevin Connor, Sensabaugh's agent, said he's asking famed orthopedic surgeon Dr. James Andrews to review the MRI results. Sensabaugh, who was injured in the first quarter of Saturday's 16-14 victory over San Diego, will miss the Cowboys' final two preseason games. Source: ESPN.com
