A clause in John Calipari's 10-year contract extension with Kentucky allows him to move into a role as the special assistant to the athletic director after 6 years.

Calipari's new extension is worth $86 million over 10 years.

Kentucky athletic director Mitch Barnhart added that the extension would see out Calipari's coaching career.

"One of the truly unique things about Kentucky men's basketball is its legacy of head coaches who have made their own lasting mark on this program. John is a perfect illustration of that. He has added a special chapter to the greatest tradition in college basketball and it's a chapter we want him to continue writing until the end of his coaching career," said the school in a statement.

Utah forward Donnie Tillman announced that he was going to sit out next season to take care of his mother, who has epilepsy.

"I respect both the University and the fans more now for understanding my wanting to be with my mother at this time, as her ongoing health issues continue. Coach [Larry] Krystkowiak believes in putting family first, and I cannot thank him enough for allowing me to follow in his lead," said Tillman in a statement.

Tillman is the reigning Pac-12 Sixth Man of the Year. 

Tillman averaged 10.5 points and 5.3 rebounds last season.

Mike Krzyzewski's grandson Michael Savarino will join Duke as a walk-on for the 2019-20 season.

Savarino appeared in a Sportscenter commercial in 2015 in which he texts Justise Winslow an emoji on behalf of Krzyzewski.

The NCAA also approved 4 more rule changes, including resetting the shot clock to 20 seconds following an offensive rebound.
