Former Buffalo Bill quarterback Jim Kelly is fighting cancer once again. He was diagnosed with jaw cancer last June, but surgery a few weeks later was thought to have ended the battle. The cancer is back and it's spreading.

Kelly's wife Jill, writes on her blog 'the cancer’s back, aggressive, and starting to spread.'

Kelly's daughter Erin is sharing Kelly's battle on Instagram.

According to CBSSports, Kelly is tentatively scheduled for surgery Thursday at a Manhattan hospital.

Thurman Thomas, Bruce Smith and Andre Reed stopped by to visit with Kelly. Erin shared the moment on Twitter.

Erin shared a special moment of the two watching the Syracuse game.

Keep Kelly and his family in your thoughts as he continues his battle.
