INDIANAPOLIS -- Colts All-Pro linebacker Shaquille Leonard, making his season debut after back surgery, has been ruled out of Sunday's game against the Tennessee Titans after suffering a concussion in the second quarter.
Leonard was injured in a collision with teammate Zaire Franklin when the two players converged on tight end Chig Okonkwo, with Leonard taking a shot to the head in the process. He went down and remained on the ground for a few moments before being helped to his feet and taken immediately to the locker room. Leonard appeared to be holding a towel over his face as he left the field, perhaps suggesting a facial injury.
