Already without the starting quarterback, the Colts may have received another injury blow on offense.
Star wideout T.Y. Hilton had a scary-looking collision with Steelers safety Mike Mitchell after a gutsy grab in the second quarter. Hilton walked off the field under his own power with the team's training staff.
Hilton was later seen going to the locker room shortly after. The wide receiver is questionable to return with a back injury, per the Colts.
Mitchell was also shaken up from the hit and suffered a stinger injury, but the Steelers announced he is expected to return.
