Patterson has spent the last two months on the Louisville staff as the co-defensive coordinator and cornerbacks coach.
"I'm sorry to see Keith leave the University of Louisville", said U of L head coach Steve Kragthorpe. "But I understand he's making the decision for family reasons, and highly respect that. Family will always be a priority in our football program."
Before leaving Kragthorpe to come to Louisville, Patterson spent the past four years on the Tulsa coaching staff. In his first three years at Tulsa, Patterson coached the linebackers when Graham was the Golden Hurricane defensive coordinator, and last year Patterson was Tulsa*s defensive coordinator and safeties coach.
"My decision to return was based on a culmination of so many factors," said Patterson. "Being here for my family as my parents are getting older is important. My relationship with Todd goes back 20 years, and I know what type of program he will continue to build at Tulsa. The way the city of Tulsa has embraced the Tulsa football program over the last four years is so rewarding to see as a native Oklahoman."
A new assistant will be sought to fill the vacancy on the current staff, but for what position, as well as the amount responsibility, is still to be determined.
The Cardinals will begin spring practice on Friday, March 30. The annual Red-White spring game is scheduled for Friday, April 20.
