Cardinals activate Wells

The Arizona Cardinals have activated running back Beanie Wells off injured reserve after he missed eight weeks recovering from turf toe.

Wells was placed on the new designated-to-return IR after a Week 3 win over Philadelphia. Under the rule, he could not practice for six weeks and could not return to the active roster for eight.

The four-year veteran began practicing two weeks ago and is expected to play Sunday against St. Louis. Coming off his first 1,000-yard season, he had run for 76 yards on 29 carries in the first three games.

Linebacker Jamaal Westerman was released to open a roster spot for Wells.
