Christian Hackenberg will forgo his senior season at Penn State to enter the 2016 NFL Draft.

Hackenberg announced his intention after the Nittany Lions' 24-17 loss Saturday in the TaxSlayer Bowl.

Hackenberg left the game with a shoulder injury.

ESPN draft analysts Mel Kiper Jr. and Todd McShay both have listed the 6-foot-4, 228-pound Hackenberg as fifth-best among draft-eligible quarterbacks and third among underclassmen.

"It was tough," Hackenberg said. "You've invested so much into a place and invested so much into fixing things and making sure it's where it needs to be."
