It's been a difficult week for Kansas City Chiefs quarterback Patrick Mahomes. On Sunday, the Chiefs failed to make history and win the first-ever Super Bowl three-peat in NFL history. And now, the Mahomes family is mourning the death of patriarch Larry "Randy" Martin, the QB's grandfather on his mom's side.

Patrick Mahomes' grandfather, Randy, is rooting for him from hospice care as the quarterback enters his third consecutive Super Bowl, his mother, Randi, tells PEOPLE. Patrick's grandfather has his bad days but is very aware of when the Super Bowl is and that his grandson is nearing another great success.
