Philadelphia, PA (Sports Network) - Philadelphia Eagles running back Brian Westbrook is officially listed as questionable for the team's game on Sunday against the Dallas Cowboys.

Westbrook suffered a concussion two weeks ago in a win over the Redskins and sat out last week when the Eagles beat the Giants. He returned to practice this week, although he sat out Friday's session.

Westbrook, 30, also sat out Week 3 against Kansas City with an ankle injury. He has scored two touchdowns while amassing just 197 yards on the ground and 130 through the air on 17 catches through five games this year.

Linebacker Chris Gocong (quadriceps, hamstring) and defensive end Victor Abiamiri (knee) are both listed as doubtful, while defensive tackle Broderick Bunkley (knee) and safety Macho Harris (ankle) are questionable.
