Louisville defensive coordinator Todd Grantham will remain with the Cardinals.
Grantham had interviewed and was offered the Oakland Raiders' defensive coordinator job, according to sources.
"I'm grateful for the opportunity to have interviewed for the defensive coordinator position with the Oakland Raiders, but I'm committed to the University of Louisville," Grantham said. "I said when I came to Louisville that I thought we could win a national championship, and we are building toward that goal with the success we had this season.
"Coach [Bobby] Petrino and Tom Jurich have given me a great opportunity and I'm grateful for their commitment. My family loves it in Louisville, and I think we are establishing something special here with head coach Bobby Petrino and our staff. Our main objective over the next week is to finish strong in recruiting and continue to bolster this signing class."
In his first year as Louisville's defensive coordinator, Grantham led a defense that led the nation with 26 interceptions.
Installing a new 3-4 defense, the Cardinals were sixth in the country in total defense (308.5 yards per game) and 10th against the run (108.9 yards per game).
"We're very pleased and happy that Todd is going to be staying at the University of Louisville," Petrino said. "He's done a fabulous job with our defense that ranked in the top 10. He's one of the finest assistant coaches in the country, and you expect excellent coaches like Todd to get opportunities in the NFL. I've always had respect for the job that Todd has done throughout his career, especially this past year at Louisville, and we're happy that he and his family will continue to be members of the Cardinals' family."
Louisville allowed 21.8 points per game last year and held four opponents to 13 or fewer points.
