Johnson will be an assistant for acting head coach Dave Padgett, who was named to the position on September 29. Padgett has been on the Louisville staff since 2014 and an assistant coach since March 2015.
Johnson coached the Horned Frogs from 2012 to 2016. His team went 18-15 and 4-14 in the Big 12 before he was fired in March 2016. Johnson was 50-79 (8-64 in conference) in four seasons with TCU. He also was the head coach at LSU (2008-12), Stanford (2004-08) and Nevada (1999-04).
“Having the experience and background Trent Johnson has is just invaluable to me,” Padgett said to Jeff Greer of the Louisville Courier-Journal.
