Trying to snap a four-game losing skid, the Broncos flew to the University of Phoenix Stadium for a Week 15 interconference fight with the Arizona Cardinals.  The last time these two teams met each other, Denver won 37-7 at Invesco Field at Mile High on December 29, 2002.  This time, it was a battle of rookie quarterbacks as Matt Leinart went up against Jay Cutler. In the first quarter, the Cardinals trailed early as Cutler completed a 54-yard TD pass to WR Javon Walker and kicker Jason Elam nailed a 30-yard field goal.  In the second quarter, Arizona trailed even further with Elam's 22-yard field goal.  The Cardinals would finally score as kicker Neil Rackers nailed a 49-yard field goal and DE Antonio Smith returned a fumble 4 yards for a touchdown.  However, Denver managed to get one last field goal before halftime as Elam kicked a 30-yard field goal.  In the third quarter, more struggles continued as Cutler completed a 10-yard TD pass to WR Rod Smith.  Arizona would respond with Rackers kicking a 38-yard field goal.  In the fourth quarter, the Broncos continued their pounding on the Cards with RB Mike Bell's 1-yard TD run.  Even though the Cardinals got a 4-yard TD run by RB Edgerrin James, Denver wrapped up Cutler's first NFL win with another 1-yard TD run by Mike Bell.  With the loss, Arizona fell to 4-10.
