Watch: SMU blocks potential walk-off FG, beats Duke in OT

SMU scored a touchdown on its possession in overtime, taking a brief 28-21 lead. But Duke responded with a touchdown of its own just a single play later.

However, the Blue Devils decided to roll the dice and attempt a two-point conversion to end the game right there and then. Quarterback Maalik Murphy rolled out to his right and tried to pass the ball into the back of the end zone for the win, but it fell short, and SMU walked away victorious.

There was a brief question of whether defensive pass interference should've been called, giving Duke another opportunity at the win. But no flag was thrown and SMU improved to 7-1 (4-0 in the ACC).

The Broncos are on the bubble to compete for the ACC title, lying in wait for either No. 9 Clemson (6-1) or No. 6 Miami (8-0) to falter for a shot at competing in Charlotte at the end of the regular season.

They now head home to prepare to host No. 19 Pittsburgh (Nov. 2), another undefeated conference foe hoping to eliminate SMU from its respective path to an ACC title and potentially the College Football Playoff.
