Jason Kelce seems inescapable on television, popping up in commercials for Campbell’s soup, the Marriott hotel chain, General Mills foods, YouTube TV, Buffalo Wild Wings and Tide laundry detergent.

Now ESPN is betting that Kelce fans want to stay up late to watch him talk some more.

Kelce, who spent his entire 13-season professional football career with the Philadelphia Eagles, is in the middle of an experiment as a late-night host on the network better known for its live sports and heated debate shows. On “They Call It Late Night With Jason Kelce,” he has judged a beer-chugging competition, driven a tiny helmet-shaped car and had conversations with the National Football League’s commissioner, Roger Goodell, and the rapper Lil Dicky.

“This is not something I think would work with just anyone, but he’s one of those guys that I believe can pull it off,” said Burke Magnus, the president of content at ESPN.

ESPN is the latest company to leverage the frenzied interest in the Kelce family. His brother, Travis, is dating Taylor Swift and is one game away from another Super Bowl berth with the Kansas City Chiefs. The brothers recently signed a distribution deal for their podcast, “New Heights,” that is worth more than $100 million, and Jason Kelce’s wife, Kylie, hosts a popular podcast of her own.

Jason Kelce, a jovial, bearded Everyman, has reached an unimaginable level of stardom for a retired offensive lineman. He is especially beloved in Philadelphia, where his hourlong show is taped in front of a live audience inside a cramped concert hall. More than 200 fans, many wearing kelly-green Eagles attire, waited in frigid temperatures to attend its premiere this month.

There were a few growing pains, with a staff member asking Kelce to rerecord an introduction to one of the segments.
