Cardinals' Wells, Heap listed as questionable

Arizona Cardinals running back Beanie Wells and tight end Todd Heap were limited in practice on Friday and are questionable for Sunday's game against the Baltimore Ravens.

Wells suffered a knee injury in last Sunday's 32-20 loss to the Pittsburgh Steelers and has rushed for 423 yards and six touchdowns this season.

If he does not play, Alfonso Smith has been tabbed as the likely starter, with Chester Taylor and LaRod Stephens-Howling also in the mix.

Heap has not played since an October 2, 31-27, loss to the New York Giants with a hamstring injury.

The two-time Pro Bowler has caught 13 balls for 150 yards this season and is looking to return to the field against the team in which he played the first 10 years of his career.

Heap racked up 5.492 yards and 41 touchdowns for the Ravens over his 10 years with the team after being taken with the 31st overall pick in the 2001 draft.
