The Hall of Famer was diagnosed with upper jaw cancer last June, and he had surgery to remove part of his jawbone. He subsequently was declared cancer-free without undergoing radiation or chemotherapy.
However, on March 14, the Erie County Medical Center announced that Kelly's cancer has reappeared.
"Jim Kelly came to ECMC this week for continued testing related to his oral surgery," said Dr. Thom Loree, a head and neck surgeon, in a statement. "Unfortunately, it has been determined that his cancer has returned.
"Our team of head and neck cancer specialists is determining a course of treatment that will allow Mr. Kelly to battle this cancer successfully. Mr. Kelly has asked that you to keep him and his family in your thoughts and prayers.
Kelly, 54, entered the Pro Football Hall of Fame in 2001 after playing from the Bills from 1986 to 1996. He holds most of the franchise passing records.
