Jim Kelly's cancer has returned.
The Buffalo Bills Hall of Fame quarterback revealed Thursday that he has a recurrence of oral cancer. It's the second time the cancer has returned after his initial diagnosis in 2013.
"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 again," Kelly said in a statement. "The oral cancer we hoped would be gone forever has returned."
The Bills added in a statement, "Jim is a tough and courageous man and we know he will fight this battle with strength and determination. The Buffalo Bills will support the Kelly family during this trying time and we ask our fans to pray for the family as Jim begins the treatment process and the road to recovery."
Kelly's announcement comes more than a month after he appeared in Auburn for an event benefiting the E. John Gavras Center's expansion project. He posed for photos, signed autographs and then spoke for nearly an hour about his life and pro football career.
He reflected on his prior cancer diagnoses and drew a connection between his health battles and the Gavras Center's daily work.
"It's all about the attitude," he said at the event. "It's all about coming together — coming together as a group, coming together as a family."
Kelly was diagnosed with cancer of the upper jaw in 2013. After receiving treatment and being declared cancer-free, he had a recurrence of the disease in 2014. He received treatment again and had been in remission for nearly four years.
After the latest diagnosis, Kelly said he was "shocked and deeply saddened." He referred to the four "Fs," which he discussed at the Auburn event in January: faith, family, friends and fans.
"With all of you by my side, we will fight and win this battle together," he said. "Staying 'Kelly Tough' and trusting God will carry us through this difficult time."
