Coming off their win over the Saints, the Falcons stayed at home for a Week 11 interconference duel with the Denver Broncos.  In the first quarter, Atlanta trailed early as Broncos FB Peyton Hillis got a 7-yard TD run. The Falcons would answer with kicker Jason Elam (a former Bronco) getting a 46-yard field goal. In the second quarter, Atlanta took the lead as Elam made a 36-yard field goal, while RB Michael Turner got a 9-yard TD run. In the third quarter, Denver retook the lead as Hillis got a 2-yard TD run.  In the fourth quarter, the Broncos increased their lead as kicker Matt Prater nailed a 20-yard field goal.  The Falcons tried to rally as Turner got a 28-yard field goal, yet Denver replied with quarterback Jay Cutler competing a 9-yard TD pass to TE Daniel Graham.  From there on out, the Broncos' defense stopped any other possible comeback attempt. With their first home loss of the year, Atlanta fell to 6-4. This was the first of only two home losses suffered by Matt Ryan in the NFL through 12/27/2010. The second was to the New Orleans Saints on December 27, 2010, the final Monday Night Football game of the 2010 season.
