Mabin will not play in the Meineke Car Care Bowl of Texas, due to a shoulder injury, which he suffered during the regular season finale against Michigan State.
NU head coach Pat Fitzgerald didn't elaborate on the injury when meeting with the media on Sunday evening, but did confirm the loss.
"Mabin is out for the year," said Fitzgerald. "I'd prefer right now not to talk about his injury, because I haven't had a chance to visit with him face to face, he went home. He had surgery that ended his season so next (media availability), I'll talk more about that."
Mabin compiled 62 tackles and one interception during his senior season, but most importantly, provided stability to a youthful defense, which faced struggles at times.
During his four-year career, Mabin, a native of Northfield Center, OH., started 49 games, while never missing a game.
"It's unfortunate for him," said Brian Peters, who has also played in every game of his career. "After going through four years completely unharmed and to have this happen, he's a tough kid and we all feel for him, he's working through it. It's just rough stuff, especially for a senior captain. It's going to be tough to fill his shoes."
NU redshirt freshman cornerback Daniel Jones stepped into Mabin's spot during the Michigan State game, and may be a candidate to make his first career start. Houston native Demetrius Dugar could also possibly get the start.
"We'll have somebody out there covering, I promise you that," said Fitzgerald. "We'll play with 11."
