ST. LOUIS (AP) -The high-flying Arizona Cardinals came back to earth hard in St. Louis. Coach Jeff Fisher's upstart Rams upset the previously undefeated Cardinals 17-3 to improve to 3-2. It's the first time since 2006 -- a span of 93 games -- that the 4-3 Rams have been over .500.Sam Bradford busted a lengthy slump with a 52-yard touchdown pass to rookie Chris Givens. Lance Kendricks caught a 7-yard TD pass in the first quarter and rookie Greg Zuerlein kicked a 53-yard field goal for the Rams.
Robert Quinn had three of the Rams' nine sacks on Kevin Kolb (kahb) to keep the Cardinals grounded. Arizona had scored at least 20 points in each of its first four games, but had no luck containing a pass rush that entered the game with only six sacks.
Arizona fell to 4-1. The only undefeated teams in the NFL are Houston and Atlanta.
