Mike Bohn has resigned as the athletic director at the University of Colorado, the school confirmed Tuesday afternoon.

Bohn's resignation is effective June 3, the school said.

Chancellor Phil DiStefano said via a news release:

"Mike Bohn led CU-Boulder athletics in a time of great transition and change. We are grateful to him for his vision, passion and commitment, and for his key role in revitalizing men's and women's basketball, helping us to join the Pac-12 Conference, and in taking important steps to upgrade athletic facilities at CU-Boulder. We wish him well."

Bohn had no comment but indicated he will conduct a media roundtable within the next day or two.

There is speculation that Bohn was forced out, as he had three years remaining on his contract.

Since being hired as AD in 2005, Bohn oversaw the school's move from the Big 12 to the Pac-12 in June of 2010, and hired nine coaches including three football coaches (Dan Hawkins, Jon Embree, MikeMacIntyre) and two men's basketball (Jeff Bzdelik and Tad Boyle).
