Super Bowl LIX between the Kansas City Chiefs and Philadelphia Eagles kicks off in fewer than 12 hours.

Star quarterback Patrick Mahomes is hoping to lead the Chiefs to NFL history as the only franchise to win three straight Super Bowl titles. Mahomes passed Joe Montana for the second most playoff wins in NFL history with an AFC title game win over the Buffalo Bills with his 17th victory – well behind the record of Tom Brady at 35.

While Mahomes chases history, he’s dealing with a devastating personal matter as his grandfather’s health continues to take a turn for the worst.

During an appearance at NFL Honors on Thursday night, Mahomes’ mother, Randi, revealed her father, Patrick’s grandfather, Randy, is “hanging on” to see him play in the Super Bowl. Late last month Randi revealed her father was moved into hospice care and has dealt with “bad days” in recent weeks, according to People.

Mahomes’ mother told People she doesn’t want to “bug” the star quarterback with updates about his grandfather, but let him know that his grandfather is “watching and he’s excited.”

Despite his bad days, Randi said her father still remembers the Super Bowl is drawing near. “The one thing that he remembers” is when the Super Bowl is. “I know that it has meant a lot to him,” she said. “And I think he’s hanging on because he wants to see his grandson do an amazing thing or just let him play.”

“I mean, he must be such a proud grandpa, so proud. And my mom was very proud and his other grandparents [were too].”

Super Bowl LIX between the Chiefs and Eagles kicks off at 6:30 p.m. EST.
