RB Felix Jones has bruised knee

CHARLOTTE, N.C. -- Felix Jones suffered a bruised knee against the Carolina Panthers on Sunday, leaving the Cowboys' running back situation in a state of flux heading into next week's key NFC East showdown against the New York Giants.

Jones, who rushed for 44 yards on 15 carries, was on the sideline for most of the final two drives during the Cowboys' 19-14 victory. His status is uncertain.

The Cowboys turned to second-year running back Phillip Tanner to handle the workload. Tanner carried three times for 4 yards on the Cowboys' final drive.

The Cowboys are hopeful DeMarco Murray can return this week after suffering a sprained left foot against the Baltimore Ravens on Oct. 14.

Murray, who was in a protective boot and on crutches last week, will have more tests Monday. Murray ran for 131 yards on 20 carries in the Cowboys' season-opening victory against the Giants on Sept. 5.
