10. Michigan MenChad Henne and Mario Manningham hand PSU lone defeat
Oct. 15, 2005: Penn State's perfect season appeared to be intact after Michael Robinson scored with 53 seconds left to give the Nittany Lions a 25-21 lead at Michigan Stadium. But a Steve Breaston kickoff return gave Michigan life, along with the controversial addition of two seconds to the clock. Quarterback Chad Henne then tossed a 10-yard touchdown pass to Mario Manningham with no time remaining as the Wolverines prevailed 27-25, handing Penn State its lone loss that fall.
