Sources: Nebraska AD Osborne to retire

The Tom Osborne era at Nebraska is coming to an end.

The former Cornhuskers football coach and current athletic director will announce his retirement from the school today, sources tell colleague Jason King. Osborne and Nebraska chancellor Harvey Perlman have a news conference scheduled for noon ET in Lincoln.

King reports Osborne isn't expected to retire immediately, although the timing of the news conference suggests some urgency.

Osborne, 75, returned to Nebraska as AD in the fall of 2007 after the school fired Steve Pederson. Osborne coached the Huskers from 1973-97, winning outright national championships in 1994 and 1995 and a shared title in 1997. A native of Hastings, Neb., Osborne came to Nebraska as an offensive assistant coach in 1964 and remained on staff until being promoted to the top job.
