Buffalo Bills Hall of Fame quarterback Jim Kelly is anticipated to have a speedy recovery and successful outcome after having surgery to remove cancer from his upper jaw, according to doctors who performed the operation.

The operation, conducted on Friday morning, was described as going "very well," according to a release issued by Buffalo's Erie County Medical Center. Kelly is recovering comfortably and will remain in hospital for an undetermined period, the release said.

The operation was performed by Thom Loree, the hospital's director of head and neck surgery department.

The 53-year-old Kelly announced Monday he had been diagnosed with squamous cell carcinoma two weeks earlier. Calling the prognosis for recovery as being "very good," Kelly said tests showed the cancer was isolated to his jaw.
