LOUISVILLE, Ky. (AP) — Louisville interim coach David Padgett has hired Trent Johnson as an assistant. The move to add the former head coach to the staff fills the vacancy created when the school named Padgett to replace Rick Pitino last month in the wake of a national federal investigation of bribery in college basketball. Johnson's 36-year career includes 17 as a head coach, most recently at TCU from 2012-16.
