Dallas Cowboys running back DeMarco Murray could return to the lineup this week after misisng six games with a sprained left foot.
Murray has practiced all week and Cowboys owner Jerry Jones indicated that the signs are positive.
"The key day was (Thursday)," Jones said. "He came back better than (Wednesday), which was his first day out, and usually that's a leveling off or setback day."
Backup Felix Jones has started in Murray's place but has been limited by sore knees.
Murray had rushed for 330 yards this season before his injury.
The Cowboys play Philadelphia on Sunday night.
