The Pittsburgh Steelers finalized their 53-man roster ahead of the 2026 season. Following the preseason finale, coach Mike McCarthy confirmed all four quarterbacks secured spots, a first for him entering Week 1. Mason Rudolph, Will Howard, and Drew Allar will back up starting quarterback Aaron Rodgers.

The team also activated cornerback Joey Porter Jr. off the physically unable to perform list after he dealt with a back injury during early training camp. Safety De Shon Elliott was placed on Injured Reserve but designated to return after recovering from a knee issue. McCarthy emphasized the value of retaining four quarterbacks, stating the room's quality enhances regular season development despite limited practice reps.

He noted the lack of time restraints during the season allows for continued quarterback development. This marks the first time McCarthy has kept four quarterbacks on the active roster entering Week 1. Rudolph, Howard, and Allar each had promising debuts against the Green Bay Packers, though subsequent performances had mixed results against the New York Jets and Buffalo Bills.
