Rodney Harrison broke his right shoulder blade against the Indianapolis Colts Sunday night and will be sidelined indefinitely. A league source confirmed the break on Tuesday night, but there?s no word on its severity or how long he?ll be out. The injury is not believed to require surgery. Harrison suffered a hairline fracture in his left shoulder in 1999 that sidelined him for 10 of San Diego?s final 11 games.
