The source said Bowles had unspecified surgery at the Mayo Clinic in Rochester, Minn., where he'd undergone tests earlier this week.
Bowles first mentioned the procedure on Twitter on Thursday morning.

Bowles, a point guard who committed to the school last November, collapsed on Sept. 3 while practicing at Wichita State's Koch Arena. He was rushed to nearby Via Christi Hospital and eventually was released on Sunday after undergoing tests.
A previous statement from the school credited the team's medical and training personnel for an efficient response after Bowles collapsed.
"I want to commend athletic trainer Todd Fagan, our athletic training staff, and emergency medical personnel, for quick and professional response exhibited in dealing with D.J.'s situation," athletic director Eric Sexton said in the statement. "In addition, a thank you to our partner, Via Christi, for the care they are providing. I visited D.J. this morning. He is in stable condition, and will have a number of tests today. We may not know much more until we receive the results of the tests. All of our thoughts go out to D.J., his family, and our men's basketball program."
The Cleveland, Tenn., native is listed as a two-star guard, according to RecruitingNation.
