Louisville has shown interest in Michigan State defensive coordinator Pat Narduzzi for their head coaching position, reports CBSSports.com's Jeremy Fowler.
Narduzzi led the Spartans' top-ranked defense this season, and was named the Broyles Award winner, given to the nation's top assistant coach.
According to the report, Louisville has five finalists for the job to replace Charlie Strong, who left Louisville this week to take the head coaching job at Texas.
Another candidate who has emerged in the search is Western Kentucky head coach Bobby Petrino, Fowler reports.
Petrino went 41-9 in four seasons at Louisville from 2003-06. He went 8-4 in his first season at Western Kentucky.
