Jason Kelce promotes Eagles Autism Challenge with social media post... after the recently retired center was spotted with brother Travis dining out in Los Angeles

Former Philadelphia Eagles center Jason Kelce is spreading the word about the Eagles Autism Challenge. 

The Challenge raises money for the Eagles Autism Foundation and sees people participate in running/walking or cycling events.

These events range from a sensory walk to a 5K up to a 30-mile bike ride - both in the city of Philadelphia and virtually around the world.

Kelce only recently retired from the NFL - back on March 4, in a ceremony attended by his family and people throughout his career.

Jason's pre-recorded video came just after he was seen dining out in Los Angeles with his brother, Kansas City Chiefs tight end Travis Kelce.

It appears that rendezvous was a business dinner - with Travis's manager Aaron Eanes seen walking out with them. 

Their dinner comes just over a week before their live New Heights show takes place at their alma mater, the University of Cincinnati, on April 11. 

The show has enjoyed great success over the past two years, earning them nominations in the Best Co-Hosts and Best Sports Podcast categories at the Webby Awards on Tuesday. 

According to The New York Times, Kelce's managers have a carefully curated plan to make him globally famous and it could even include a film about the three-time Super Bowl winner.

The Eanes brothers spoke to NYT last year about their plan to build Travis's profile beyond football - and there is thought that he could one day swap Kansas City for Hollywood. 

The publication says 'film scripts have been passed around' and that game shows are also under consideration. 

Meanwhile, amid their joint success on New Heights and Jason's foray into life after the NFL, it appears the retired center could also be looking to establish a business empire of his own. The Super Bowl winner is already believed to be in high demand with multiple networks clamoring for his services after stepping away from the field at the end of the NFL season.

But it appears he's hoping to still live in Philadelphia - with the ex-center throwing out the first pitch at a Phillies game in recent days.
