Patrick Mahomes has a lucky pair of red underwear that he wears for every game

• Kansas City Chiefs recently edged Philadelphia Eagles to win the Super Bowl.
• It might have all been down to the lucky red underwear that Patrick Mahomes always seems to wear.

Patrick Mahomes has a lucky red pair of underwear, and his Kansas City Chiefs teammate Chad Henne wants you to know all about it.

Mahomes recently helped lead the Chiefs to a 38-35 victory over Super Bowl rival Philadelphia Eagles to claim a second championship win of his own.

Throughout the NFL, though, he apparently has a stringent routine locked down that includes ensuring he's got the same briefs. The only question is whether they're Hanes or Lululemon.

"He has a baseball background, so he has to have a certain thing each and every day," 37-year-old Henne, the backup quarterback at the Chiefs said of the team's star during an appearance on The Adam Schefter Podcast.

"He comes in, he does his work. His notes are written out a certain way. Same pair of underwear, which probably not a lot of people know, on game day. He's been wearing it since I've been part of it."

As Henne joined the Chiefs in 2018, after previous stints with the Miami Dolphins and Jacksonville Jaguars, it means Mahomes has been wearing red underwear on game day for at least five years.

"You glimpse up, and you're like, 'Damn, kid's wearing them again'"

Elaborating on the lucky red briefs, Henne said of Mahomes: "I'm not sure if they're Hanes or if they're Lululemon, but it's one or two of those brands, and ever since he comes in the locker room — boom, it's right there."

He continued: "I'll be stretching, and like I said, you just glimpse up, and you're like, 'Damn, kid's wearing them again.'

"This definitely has to be a superstition and a good-luck charm, for sure."

As Insider's Tyler Lauletta reported last week, not everybody involved in this year's big game is superstitious.

Eagles head coach Nick Sirianni said he doesn't like when people knock on wood around him and prefers routine over superstition.

Considering the Eagles lost the Super Bowl, though, maybe Sirianni should start wearing some lucky briefs of his own.
