Jason Kelce will not be at his brother Travis’ Kelce Jam music festival on May 18 in Kansas City.

On Tuesday, the Chiefs star announced the return of the Kelce Jam, headlined by Lil Wayne, Diplo, and 2 Chainz. This year’s festival will run from 5 PM – 12 AM at The Azura Amphitheater and feature booths from partners including Wingstop, Uber Eats, Casa Azul, and Medium Rare.

Jason, however, will miss the festivities as he helps host the Eagles Autism Challenge in Philadelphia on the same day. On Tuesday, the recently-retired Eagles center sent a special message to fans to promote the charity event.

‘What’s up Eagles fans,’ he said. ‘If you’re like me, you’re excited for the Eagles Autism Challenge this year. You can run, walk, do what you want, really. As long as you enter and come on board, you can help support Eagles Autism-related care and research. And let me tell you, this community needs it.’

‘We love your support. We’d love to see you come on out [on] May 18th. Please stop by.’

Taylor Swift will also miss the Kelce Jam due to her Eras tour being in Sweden late in May

In 2023, the Kelce Jam was highlighted by Kelce’s viral spike of the Lombardi Trophy during an on-stage performance with Machine Gun Kelly. Last year’s lineup featured Loud Luxury, Rick Ross, and Tech N9ne.

Jason and Travis’ mother, Donna, also memorably danced on stage in front of thousands.

Unfortunately, Travis’ popstar girlfriend, Taylor Swift, will also miss the Kelce Jam. Their romance flooded headlines this past NFL season after making their relationship public in late September.

Swift’s record-breaking Eras tour will start its European leg on May 19. On the 18th, the show will be on Scandinavian soil as the 14-time Grammy winner takes the stage in Stockholm.

As for Kelce, the festival will be his last hurrah before OTA offseason workouts begin for the Chiefs ahead of their title defense and three-peat attempt.
