Watch: Appalachian State shocks Troy with last-second Hail Mary

After upsetting No. 6 Texas A&M last week, what did Appalachian State have in mind for an encore?

You win if you had a "last-second Hail Mary for the win" on your college football bingo card. 

App State followed up last week's astounding feat with another on Saturday. Trailing Troy 28-26 late in the fourth quarter, a miracle happened. Facing fourth down near midfield with only two seconds remaining on the clock, quarterback Chase Brice called for the snap before launching a pass toward the end zone. 

Brice's pass came up short of the end zone, but divine intervention seemingly took over. 

A Troy defender attempted to make a heads-up play by batting the football down to the ground. Unfortunately for Troy, the football found the waiting arms of Christian Horn, who quickly turned the corner and ran into the end zone to give the Mountaineers a 32-28 win. 

Saturday's walk-off victory capped off a great day on the Appalachian State campus. College GameDay held its live broadcast at App State, allowing students to show off their creative sides with hilarious signs poking fun at Texas A&M. 

The Mountaineers' remarkable victory moves them to 2-1 on the young season. Next Saturday, they'll look to make it three wins in a row when they host James Madison at Kidd Brewer Stadium.
