​The Washington ​Redskins already have question marks surrounding the running back position with exactly two weeks left before they kick off the 2016 season. Now, according to team sources, rookie running back Keith Marshall is expected to miss at least three weeks.

For Marshall, this could hurt his chances of making the final 53-man roster. The Redskins will now have to rethink their strategy and determine if they want to sign a running back off the market, or if Marshall is worth waiting out the injury. In three preseason games Marshall carried the ball 16 times for 28 yards.

An interesting side-note from the report -- the team's intention is to re-evaluate Marshall in three weeks which means this injury could in fact keep him out longer. With Matt Jones already injured this can't sit well with Redskins head coach Jay Gruden.

The team has Chris Thompson, Mack Brown and Robert Kelley as it's three active running backs currently on the roster. Thompson is looked at as more of a pass-catching third-down back, so basically it leaves a second-year power back in Brown and the rookie Kelley, neither of which have ever started an NFL game.
