"Everything started July 24 when Sherels noticed blood in his stool. He went through a series of tests and scans that ruled out common gastrointestinal disorders but failed to locate the source of his bleeding. His blood loss caused his hemoglobin level to drop, requiring a series of transfusions.
Growing concerned, Sherels consulted with Gophers team doctors and was admitted to the university hospital. Doctors repeated previous tests as Sherels continued to lose blood.
One night, he got up at 4 a.m. to use the bathroom and passed out. His hemoglobin had dropped to a very low level.
When he regained consciousness, doctors were surrounding him in bed and were preparing defibrillation.
An angiogram finally discovered the source of bleeding in an area at the entrance of his large intestine. Doctors found and repaired an abnormal cluster of blood vessels, a condition known as angiodysplasia."
