LINCOLN, Neb. (AP) Nebraska defensive back Charles Jackson will undergo season-ending surgery on his left knee.
Coach Bo Pelini announced Thursday night that Jackson sustained ligament damage when he was injured in practice on Tuesday.
Jackson was projected to be the starter at the nickel position. The junior from Spring, Texas, played in all 13 games last season on special teams and as a backup safety. Pelini said Jackson will use his redshirt this season and have two years of eligibility remaining.
Pelini said junior Byerson Cockrell and freshmen Josh Kalu and Trai Mosley would compete for playing time at nickel.
