Sad news for Buffalo Bills legend Jim Kelly ... who just announced his oral cancer has returned.
Kelly was initially diagnosed with oral cancer back in 2013. He beat it once -- and then it resurfaced. He beat it again. Now, Kelly says he's facing round 3.
"The oral cancer we hoped would be gone forever has returned," Jim said in a statement.
"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."
"Although I was shocked and deeply saddened to receive this news, I know that God is with me.
