Steelers' Conner injures AC joint, leaves with arm in sling

Pittsburgh Steelers running back James Conner was forced to the sidelines and taken to the locker room with a shoulder issue late in Monday night's win over the Miami Dolphins.

Head coach Mike Tomlin told reporters after the game that Conner suffered an AC joint injury, and the runner was later seen with his right arm in a sling, according to NFL Network's Mike Giardi.

Tomlin added that Conner will be evaluated on Tuesday.

The 24-year-old Conner was enjoying his most productive game of the season before the fourth-quarter exit, taking 23 carries for 145 yards and one touchdown.

Steelers backup running back Benny Snell, who was drafted in the fourth round this year, also left the prime-time contest with a knee injury.

If Conner and Snell both miss time, Jaylen Samuels could be set for a major backfield role. Samuels appears to be nearing a return to action after undergoing a knee scope in early October. He was a full participant in practice throughout this week before ultimately being held out for a second consecutive game.

Pittsburgh, now 3-4 after Monday's win, will host the Indianapolis Colts on Sunday afternoon in Week 9.
