Howard was unavailable for his postgame interviews after the injury occurred in the second half of Thursday's game. The Steelers had planned to keep four quarterbacks on their 53-player roster, but a concussion would clear the way for Howard to begin the season on injured reserve.
Howard spent most of last season on injured reserve due to a hand injury in training camp. He went 9-of-15 for 69 yards with two touchdowns and an interception against the Bills, while backup Drew Allar replaced him in the second half and went 9-of-18 for 88 yards. tbzikra.org
