Buffalo Bills Hall of Fame QB Kelly says his cancer has returned

Buffalo Bills Hall of Fame quarterback Jim Kelly has once again been diagnosed with oral cancer.

Kelly released a statement Thursday through his publicist saying he is 'shocked and deeply saddened' by the news, and vows to once again fight to overcome the disease. He did not go into specifics on the diagnoses except to say the cancer was discovered following a test.

'As our family has faced many trials and triumphs throughout the years, you have blessed us with your prayers. We are asking for those prayers once again,' Kelly said. 'With all of you by my side, we will fight and win this battle together.'

Kelly's wife, Jill, posted a note on her Instagram account accompanied with a picture (above) of her with her arm around her husband. 'We are shocked, heartbroken, sad, angry, confused and just darn tired,' Jill Kelly wrote. 'Yet despite how we feel, we KNOW that God is a promise maker and keeper. ... The more life and heartbreak I experience, the more I realize that this is not the end of the story'

Kelly then closed his statement by saying: 'Staying 'Kelly Tough' and trusting God will carry us through this difficult time.'

The diagnosis comes a few weeks after Kelly celebrated his 58th birthday.

Kelly had been cancer-free since September 2014, but had been required to undergo routine follow-up testing.

He was first diagnosed with squamous cell carcinoma, which led to him having surgery to have a portion of his upper jaw removed in June 2013.

Follow-up tests nine months later showed the cancer spread to his sinus, which led to radiation and chemotherapy treatments. Kelly lost 70 pounds while being treated.
