Steelers running back James Connor suffered an AC joint injury during the win over the Dolphins Monday night. Connor was injured near the two-minute warning after rushing for 145 yards and a touchdown. The Steelers have a short week leading into Sunday’s home game against the Indianapolis Colts. Also, backup running back Benny Snell Jr., who had five carries for 13 yards, is being evaluated for a knee injury. That leaves the Steelers with Trey Edmunds as the only healthy running back on the 53-man roster. Running back Jaylen Samuels is coming off arthroscopic knee surgery earlier this month and was inactive for the Monday night game.
