Hall of Fame college basketball legend Jim Calhoun is calling it a career. And what a successful one it was.

Calhoun led the Huskies to three National Championship in his 25-year tenure with the school, retiring tenth on the all-time wins list with 873.

The 70-year-old, who is the oldest coach to ever win a Division 1 national title, was also well known for overcoming battles off the court, including a bout with prostate cancer, squamous cell carcinoma and spinal stenosis.

Following an accident that left him with a broken hip last month, Calhoun leaves as his team is ineligible for the 2013 NCAA Tournament, due to a low team APR - the NCAA's punishment for low academic scores.

ESPN.com reports his full retirement won't come immediately:

Calhoun will take a transition appointment through next spring as a special assistant to athletic director Warde Manuel. When fully retired, he will become head coach emeritus.
