Amendola was limited on Monday, but took a full complement of reps Tuesday, according to St. Louis Post-Dispatch reporter Jim Thomas.
Amendola leads the Rams with 31 catches and 351 receiving yards, as well as touchdowns on trick plays. Amendola grabbed a 2-yard touchdown on a fake field goal pass from placeholder Johnny Hekker in the Rams' 19-13 win over Seattle in Week 4.
The Rams face the surging Cardinals in front of a primetime audience Thursday. A healthy Amendola will definitely improve St. Louis' chances of beating Arizona for the first time in St. Louis -- the Cardinals' former home city -- in the last eight attempts.
