GLENDALE, Ariz. (AP) Quarterback John Skelton is available for Arizona's game against the Buffalo Bills on Sunday, but tight end Todd Heap and cornerback Greg Toler are not.
Skelton has been out since spraining his right ankle against Seattle in Arizona's opener, and Kevin Kolb has led the Cardinals to a 4-1 record. Kolb is listed as the starter against Buffalo.
Running back LaRod Stephens-Howling also returned after missing two weeks with a hip injury.
Heap misses his third straight game with a knee injury and Toler is out with a hamstring injury.
Bills defensive tackle Kyle Williams is active for Sunday's game despite missing two days of practice with an ankle injury, but defensive end Mark Anderson is still out with a knee injury.
