One thing is for sure, the Eagles will not be facing DeMarco Murray, who is out for the year with a broken ankle. First round bust Felix Jones has been filling in for Murray, but he missed practice yesterday with a hamstring injury. It's not known yet whether he's just getting a day off or whether his availability is in doubt. He did not finish last week's game against the Bucs.

Jamar Chaney says that if they do face Jones this weekend, they won't take him lightly

"He's a first round pick so he has a lot of talent. I saw Felix in college a bunch of times at Arkansas and he's a great back. I mean, the thing that's surprising about him is how fast and quick he is. I mean, he has pretty good acceleration and can get to top speed pretty fast. I guess he has a chip on his shoulder because he's not starting anymore, but he's starting now because Murray went down and I guess he has a chip on his shoulder now and wants to prove people wrong."

If Jones can't go, 12 year vet Sammy Morris will likely carry the load for Dallas. He had 53 yards on 12 carries against the Bucs last week after Jones went down. Morris hasn't started a game since 2009 and hasn't really seen significant action since the 2008 season in New England when he rushed for a career high 727 yards.
