AMES, Iowa -- Iowa State coach Bill Fennelly will begin treatment for what the university says is an invasive cancerous lesion on his vocal cords.

ISU issued a statement Thursday saying doctors found the lesion during a recent exam. Fennelly will undergo radiation treatments for five weeks beginning later this month. The university says doctors "indicate a full recovery is expected."

Fennelly says in the statement that he will face his health challenge "head on" and he will continue to work with his staff and players.

Fennelly is now in his 17th season with the Cyclones. He has received approval from his doctors and family to continue coaching.

The statement says the coach and ISU will have no further comment, and Iowa State practices will be closed until further notice.
