Jason Kelce's wife Kylie could have baby during Super Bowl

PHOENIX, Ariz. -- With brothers Jasonand Travis Kelce facing off each other Sunday, Super Bowl LVII (6:30 p.m. ET, Fox) between the Philadelphia Eagles and Kansas City Chiefs is already a family affair. There's another layer to the story that could really make this the "Kelce Bowl."

Jason's wife, Kylie, is 38 weeks pregnant. She has made the trip to Arizona with her parents and obstetrician should the big moment happen in the big moment.

"We haven't talked too much game plan if it happens during the Super Bowl. But I like to think my wife will not tell me and just find a way to hold off hopefully till after the game for the actual delivery," Jason said. "But if it happens during the game, don't even put that in my head, please."

Kylie and Jason are already parents of two daughters. Their daughter Wyatt recently showed off her team spirit by singing the Eagles' fight song in her crib.

Football has come in handy during Jason's time as a father.

"A lot of the nurses at the maternity ward where we had our first two, they all said, 'You're going to be a natural at holding your baby because the best way to hold them is just like a football.' It's crossed over well. Good for me I have good security when I'm holding the rock so no fumbles yet," he said.
