Philadelphia, PA -- (Sports Network) - Philadelphia Eagles cornerback Asante Samuel sat out practice Wednesday, while running back Brian Westbrook was a full participant in practice in preparation for Thursday night's matchup against the Arizona Cardinals.

Samuel, who suffered a neck injury in the first quarter against Baltimore last Sunday, is listed as doubtful for the game. He logged one tackle in Sunday's defeat and has three interceptions and 27 tackles through 11 games this season.

Westbrook, who managed only 39 yards rushing on 14 carries against the Ravens, is still nursing knee and ankle injuries and is listed as questionable for Thursday. The Villanova product has amassed 547 yards on the ground with six touchdowns in addition to 34 receptions for 213 yards and two scores for the Eagles, who are in last place in the NFC East with a 5-5-1 record.

Defensive end Darren Howard, who did not practice on Tuesday, was a full participant in Wednesday's practice and is listed as probable.
