KNOXVILLE, Tenn. — Tennessee basketball coach Pat Summitt had offseason shoulder surgery, not for a sports injury but because of a tussle with a raccoon.

The winningest basketball coach in NCAA history has had problems with her right shoulder since dislocating it while chasing away a raccoon poised to attack her Labrador. The attack came near her home on March 5, just days before the Southeastern Conference tournament.

A month later, Summitt guided the Vols to their eighth NCAA title.

Summitt had arthroscopic surgery Thursday in Knoxville, Tenn., to repair recurring instability problems.

The coach will begin rehab in about a week. The Lady Vols begin practice on Oct. 17.
