LOUISVILLE COACH OUT

Chris Mack is out as Louisville men’s basketball coach after he and the school agreed to part ways. Assistant Mike Pegues has been named interim coach for the remainder of the Cardinals’ season.

The agreement was announced Jan. 26 following a special joint meeting of the school’s Board of Trustees and the University of Louisville Athletic Association board. Interim athletic director Josh Heird said Mack will be paid $4.8 million between this fiscal year and the next three fiscal years.

Mack leaves after going 6-8 since returning Dec. 1 from a six-game suspension by the school for failing to follow university guidelines in his handling of an extortion attempt by fired Cardinals assistant coach Dino Gaudio last spring. Pegues guided the Cardinals to a 5-1 start while Mack sidelined and now will try to lift the team out of a slump that includes five losses in its last six games.
