James Conner suffered an AC joint injury on Monday night and left Heinz Field with his right arm in a sling.

Conner rushed 23 times for 145 yards and a touchdown in the Pittsburgh Steelers 27-14 win over the Miami Dolphins.

He was injured near the two-minute warning in the fourth quarter.

The Steelers could have issues at running back against the Indianapolis Colts on Sunday. In addition to Conner's injury, Benny Snell is being evaluated for a knee injury. Jaylen Samuels is coming back from arthroscopic knee surgery performed less than a month ago.

Mike Tomlin has been linked to the Washington head coaching job despite having two seasons remaining on his contract with the Pittsburgh Steelers.

Washington would have to blow Pittsburgh away with an offer for Tomlin while also giving hi a substantial contract.

"Neither of which is going to happen," one source close to the situation told ESPN.

"I don't see Mike going to Washington," the source continued. "That is so far-fetched. It's so far out there. It would have to be a deal that the league never has seen before and would change the way business is done in football, and I don't see that happening."

Mike Tomlin, Todd Bowles and Eric Bieniemy are three possible candidates for Washington's head coaching vacancy, according to a source close to Dan Snyder who is familiar with his thinking at the moment.

Washington fired Jay Gruden on Monday following a 0-5 start to the season.

Tomlin has been head coach of the Pittsburgh Steelers since 2007.

Bowles was previously head coach of the New York Jets and is currently defensive coordinator of the Tampa Bay Buccaneers.

Bieniemy is offensive coordinator of the Kansas City Chiefs.

Mason Rudolph says it's just a "matter of time" before everything clicks for the Pittsburgh Steelers offensively.

In Week 4, JuJu Smith-Schuster had just three catches for 15 yards.

"Got to get the ball to your best players, and that's something you look forward to every week in the gameplan, so it's just an emphasis on my end," Rudolph said. "JuJu is a team player, and there's going to be games like that where they might take him away or other guys have to step up and make plays and they did that Monday night. That's the type of group we have."

NBC has decided not to flex the Week 6 game between the Los Angeles Rams and San Francisco 49ers to Sunday Night Football.

NBC will instead keep the Los Angeles Chargers hosting the Pittsburgh Steelers.

The Rams lost last week to the Tampa Bay Buccaneers and play at the Seattle Seahawks in Week 5. The undefeated 49ers host the Cleveland Browns on Sunday Night Football.
