Legendary former Nebraska football coach Tom Osborne, who has served as the school's athletic director for the last five years, announced Wednesday that he would step down Jan. 1.
"At some point, whether you're able to function or not, just the perception that you're getting old can get in the way," Osborne, 75, said. "I don't want to be one of those guys everybody is walking around wringing their hands trying to figure out what are we going to do with him? That happens sometimes."
Osborne, who had double-bypass heart surgery in 1985, said he has no health issues that led to his decision.
"I'm probably healthier today than when I was a member of Congress. That takes a big toll on you," he said.
Osborne was a member of the House of Representatives from 2000 to 2006 and lost to incumbent Dave Heineman in the 2006 Republican gubernatorial primary.
