"David has had a phenomenal year and is very deserving of this honor," said NC State head coach Tom O'Brien. "To be a finalist for such a prestigious award as a sophomore is a real testament to his performance this season."
In the Wolfpack's win over then-No. 7 Clemson, Amerson tied the ACC single-season record that was set 15 years ago by UNC's Dre Bly. He is one pick from ranking in the top 10 in NCAA-FBS history.
Earlier this season, the Greensboro native broke the NC State single-season mark that had stood since 1938. Amerson has picked off a pair of passes in three different contests and returned one for a touchdown in the win at Virginia.
Last week Amerson won the 2011 Jack Tatum Award, which is also given to the top defensive back in college football.
The presentation of the Thorpe Award will be featured on The Home Depot College Football Awards live on Thursday, Dec. 8 at 9 p.m. on ESPN.
If he took home the hardware, Amerson would be the Wolfpack's first Jim Thorpe Award winner.
