The injuries are piling up in Pittsburgh.

Steelers second-year running back Jaylen Samuelsunderwent arthroscopic knee surgery Monday and is expected to be out amonth, Steelers coach Mike Tomlin Tuesday.

Samuels, whohas 18 carries for Julio Jones Jerseys 50 yards and a touchdown, 13 catches for 83 yards and has completed 4 of Teair Tart Jerseys 5 pa ses for 35 yards and an interception this season, suffered the injury Sunday against Baltimore and was seen on crutches at the team's practice facility Tuesday.

"We had him evaluated and saw that that was nece sary, so we made the decision to fix it ASAP and it was fixed yesterday," Tomlin said.

Marcus Johnson Jerseys Tomlin added that quarterback Mason Rudolph remains in the concu sion protocol after being knocked unconsciousby Ravens safety Earl Thomasbut "appears to be doing fine." There's no timetable for his return, though he's unlikely Jordan Roos Jerseys to play in Week 6, especially Anthony Firkser Jerseys with the team'sWeek 7 bye looming.

Should he be ruled out, backup Devlin Hodges will be ready to fill in under center in Rudolph's absence once again.

As for the malfunctioning medical cart that also caused a stir, Treylon Burks Jerseys Tomlin explained it was a non-i sue.

"Mason Rudolph walked off the field because he chose to and medical experts were comfortable for him to do so. The medical cart not functioning was irrelevant."

Other injuries: CB Steve Nelson Marcus Mariota Hoodies Sweatshirts (groin), WR James Washington (shoulder), Mark Barron (hamstring). Tomlin said Washington and Barron can be listed as questionable for Chargers.

With the undermanned Steelers set to travel to Jeffery Simmons Jerseys Los Angeles this week, Tomlin refused to addre srumors that he is the leading candidate for theRedskins' coaching vacancy after Jay Gruden was fired Monday.

"Im not worried about Derrick Henry T Shirts that,"Tomlin said. "Im the head coach of a 1-4 football team thats going on the road to play a Hall of Fame quarterback with a third-string quarterback. Do you think Im worried about anything other than that?"

The Steelers (1-4) are slated to visit the Chargers (2-3) at 8:20 p.m. ET Sunday.
