Lincoln, Neb. ? Marvin Sanders, who coached one of the top pass defenses in the nation, has resigned as Nebraska’s secondary coach.

Coach Bo Pelini announced Sanders’ departure in a statement Thursday, a day after Indiana coach Kevin Wilson said at his signing-day news conference that Corey Raymond was leaving the Hoosiers’ staff to coach Nebraska’s secondary.

Raymond would not confirm his move to Nebraska when reached Thursday, referring questions to Pelini.

Pelini said in his statement that he was “working toward finding a replacement for coach Sanders” and that an announcement would be made “when the hiring process is completed.”

The secondary coach’s job is the second opening on the defensive side. Pelini also is looking to hire a linebackers coach after Mike Ekeler left in December to become co-defensive coordinator at Indiana.
