The 6-foot-6, 265-pound Bowles, a former All-Stater from Glasgow High School, said on his Facebook page that his current medical condition comes from a childhood issue.
"I have what's called a Chiari malformation, which basically means part of my lower skull didn't form right as a child," Bowles said. "Over time it's pushed on my spine causing a cyst to actually form inside my spine. I will be having surgery this Thursday to remove those parts in my lower skull/upper neck."
U of L coach Charlie Strong confirmed that Bowles will have surgery but said it's likely not a surgery that will force his career to end.
Bowles said he has been told he would be able to continue to play as long as the cyst disappears.
Bowles was a first-team All-State selection and finished his career at Glasgow with 70 catches for 1,018 yards and 13 touchdowns. He had 20 catches for 346 yards as a senior.
