Jason Kelce, Super Bowl champ and star Philadelphia Eagles center, retires

Philadelphia Eagles center Jason Kelce announced his retirement from football on Monday, wrapping up a stellar 13-year career that brought fame and notoriety rarely enjoyed by an offensive lineman.

He thoroughly enjoyed the rest of January and Super Bowl Sunday on Feb. 11, partying — not always fully clothed — at the playoff games of his brother Travis.

When the Chiefs beat the Buffalo Bills in the conference semifinals on Jan. 21, Kelce's act in the stands — to help 8-year-old Ella Piazza gain a brief-but-memorable audience with Swift — was almost as memorable as any play on the field.

Kelce's shirtless antics weren't totally embraced by his wife, Kylie Kelce.

“I’m like, ‘Hey I’m just letting you know what’s happening. I’m not asking for permission, I’m doing this,'” he said on “New Heights,” the hit podcast he co-hosts with Travis.

After Kansas City's thrilling overtime win against the San Francisco 49ers at the Super Bowl on Feb. 15, Jason Kelce stole the show
