The University of Louisville has pegged Jon Gruden as its No. 1 candidate should the school decide to fire coach Steve Kragthorpe, sources told NFL Network’s Michael Lombardi.

Gruden went 95-81 in 11 seasons with the Oakland Raiders (1998-2001) and Tampa Bay Buccaneers (2002-08). He led the Bucs to a Super Bowl XXXVII victory over the Raiders in his first season after leaving Oakland and lasted seven years in Tampa Bay before he was fired.

Gruden has never been a college head coach, but he served as an assistant at Tennessee (1986-87), Southeast Missouri State (1988), Pacific (1989) and Pittsburgh (1991). And his brother, Jay, played quarterback at Louisville from 1985 to 1988.

Kragthorpe is 13-16 in two-plus seasons at Louisville, which hired him from Tulsa in 2007. He took over from Bobby Petrino, who left to take the Falcons’ head-coaching job and lasted just 13 games, going 3-10.
