Allar (coach's decision) is inactive for Sunday's game against the Falcons.
The Steelers opted to carry four quarterbacks on the 53-man active roster. Allar will observe Sunday's regular-season opener in street clothes while Will Howard (coach's decision) serves as Pittsburgh's emergency third quarterback behind starter Aaron Rodgers and backup Mason Rudolph. Allar figures to be a healthy scratch for most, if not all, games this season unless one of Rodgers, Rudolph or Howard were to miss time.
