LINCOLN, Neb. -- Nebraska nose tackle Jason Lohr will miss the rest of the season after surgery on his left knee.

Lohr, a 6-foot-2, 275-pound senior from Tulsa, was a second-year starter. He tore a ligament during a pileup in the first quarter Saturday in the No. 4 Cornhuskers' 27-10 victory over Notre Dame.

Lohr had four tackles in the first two games this season, including 2½ sacks. He had 46 tackles last year and 33 as a sophomore.
