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.
