Cowboys rookie DeMarco Murray and veteran Tashard Choice will share the rushing load Sunday against the Rams, owner Jerry Jones said Friday. Dallas starting running back Felix Jones will not play Sunday because of a high left ankle sprain suffered last week at New England. "We've shown that we've split the carries and, in this circumstance, that's very appropriate since DeMarco is still very early on in his repetitions, his time that he's sorted through the blocking," Jones said on his weekly radio show on KRLD-FM. "What happened to us last week is we did get, what I call 'big-boyed' and they really did put a lot of pressure on the interior of our line and when they saw it working they kept it coming and we had to really adjust for that and we got a lot of plays that were behind the line of scrimmage. But I do expect us to adjust for that."
