LINCOLN, Neb. (AP) – A University of Nebraska regent says he fears for the safety of the Cornhuskers’ football traveling party and fans at Saturday’s game at Penn State. He wants assurances a security plan is in place to protect them.  Regent Tim Clare of Lincoln said he began worrying about safety while watching televised coverage of the scene in State College, Pa., after coach Joe Paterno’s firing Wednesday night. He said Penn State has a raucous atmosphere on a normal football Saturday, and the school owes Nebraska answers.  Penn State police chief Tyrone Parham wrote in an email to the Associated Press on Thursday that his force is “taking extra precautions and has added additional resources for the game.”  Nebraska athletic director Tom Osborne declined to comment.
