Coming off their bye week, the Cardinals flew to Raymond James Stadium for a Week 9 intraconference duel with the Tampa Bay Buccaneers.  In the first quarter, the Cards flew first with kicker Neil Rackers getting a 47-yard field goal.  However, the Buccaneers took the lead with QB Jeff Garcia completing a 37-yard TD pass to WR Joey Galloway.  In the second quarter, Arizona continued to struggle as Tampa Bay kicker Matt Bryant nailed a 32-yard field goal for the only score of the period. In the third quarter, the Cardinals continued to trail as Buccaneers RB Earnest Graham got a 2-yard TD run.  In the fourth quarter, Arizona began to fight back as RB Edgerrin James got a 3-yard TD run.  Late in the game, during the Cards last offensive drive, QB Kurt Warner would get intercepted by Safety Jermaine Phillips.  Even though replays clearly showed that he didn't stay in bounds, Arizona was out of timeouts and therefore were unable to challenge the play. It would be remembered as the most controversial call in 2007.
