The Dallas Cowboys will likely be without running backs DeMarco Murray and Lance Dunbar for Sunday's game in Philadelphia, Jerry Jones said.
Dunbar strained his right hamstring during the loss to Denver on Oct. 6. Murray sprained the MCL in his left knee during the second quarter on Sunday.
"He's probably going to be out," Jones said of Murray on 105.3 The Fan [KRLD-FM]. "We'll miss him certainly this coming week and then we'll see from there. I can't emphasize enough how much doctors and trainers depend on the response of a player when you're rehabbing injury, because all players have injury and some of them have it in an area that can be more limited, relative to their ability to long term – long term being in this case, playing throughout the season.
"You can still get plays out of them, but they're not the quality plays that you'd like to get later on, so putting them active, you put that off."
And Jones said of Dunbar: "He won't be available for us Sunday, but is a real weapon for us. We need to get him back."
Murray leads the Cowboys in rushing with 428 yards and three touchdowns on 91 carries. Dunbar is the team's second-leading rusher with 38 yards on seven carries.
Joseph Randle will likely get the start in their absence. The fifth-round pick in this year's draft carried 11 times for 17 yards and a touchdown against Washington.
"There's some real similarity as to their running style between Murray and Randle," Jones said. "[Randle's] very quick. He's got good size. He's very capable of doing what he needs to do on third down with his blocking responsibility. He's also outstanding as a receiver.
"When you look back at his production at Oklahoma State, in the Big 12, we were impressed enough not only to draft him but I think he has a chance to be a real asset to us in our running game."
