It's simple: Sit him.
Murray is doubtful for this game (via ESPN.com), but don't start him even if he does play. He has been dealing with a foot injury for most of this season. It looks like it will keep him from playing again this week, so make sure your fantasy team has other options.
Washington's defense ranks in the top 10 in defending the run, and Dallas ranks near the bottom of the NFL in rushing yards per game. That combination means the running back would have a difficult time getting anything going.
The 24-year-old has not played since October 14 against the Baltimore Ravens. In five games this season, he has only topped 100 rushing yards once, which happened to be in the opening game of the season. He has not had more than 20 carries in a game this season, and he has averaged under four yards per carry in three of the five games.
Despite having the ability to be an explosive runner, he managed to find the end zone on the ground only once when he was healthy this season.
So far this season, Murray has proven he can be a dual-threat running back. He has averaged over 20 receiving yards per game this season, which would help his fantasy numbers. However, he does not have a receiving touchdown this year.
The short week will not help Murray either. The team would struggle to add him into the mix after a difficult game last week, and playing on Thursday this week makes it even tougher for Murray to be a factor.
Dallas escaped in overtime against the Cleveland Browns last week, and Thursday's game will be an even bigger challenge as they have to face Robert Griffin III on a short week. These two teams have not met this season, so there is a little bit of mystery as to what kind of a game this will be.
The Redskins have been one of the most explosive offenses in the NFL this season, and this game could turn into a shootout. If RGIII has his typical game, the Cowboys won't be able to stay with the running game.
RGIII can put up points, and so can Tony Romo. This has the makings of an exciting game, and the Cowboys will not have the ability to run the football. They will need to be able to put points in a hurry, but the Redskins don't allow teams to run the ball effectively.
For the rest of the season, it would be smart to keep Murray on your fantasy roster. He hasn't played in over a month so most fantasy owners have been able to find another running back to use during his absence.
Wait at least one more week before considering giving Murray a start. The short week hurt his chances to play in Week 12, but there is hope that he plays next week.
