Kelly, who led Buffalo to four consecutive Super Bowls in the 1990's, was treated for sinus cancer this summer. Tests in August found that Kelly was cancer-free.
Sunday's game will the Bills' first home game since the Buffalo area was buried under up to seven feet of snow. The storm forced the NFL to move last week's game against the Jets to Detroit.
Kelly was honored in October by the University of Miami, his alma mater. Kelly was the Grand Marshal of the school's homecoming festivities and served as an honorary captain for the Hurricanes' game against North Carolina. The team also wore "Kelly Tough" decals on its helmets.
