Though it’s unknown whether rookie DeMarco Murray’s 253-yard effort from last weekend will move him up from No. 3 on the depth chart, he’ll continue to be the lead dog on Sunday night in Philly, when the Cowboys face the Eagles.
The Cowboys don’t have another running back who could be elevated from the practice squad. Barring the highly unlikely decision to sign a guy off the street (Brian Westbrook, anyone?), it will be Murray and Tanner on Sunday night.
