Why Jimmy Fallon, Keegan-Michael Key are at the Lions game

When the Detroit Lions kicked off their 2025 home opener against the Chicago Bears, they did so with a couple of notable celebrities in the building.

"Tonight Show" host Jimmy Fallon and Michigan-born actor Keegan-Michael Key were featured guests at Ford Field for Sunday's Week 2 matchup. Fallon was visible on the broadcast pumping up the crowd while waving a Lions "One Pride" flag as Key applauded and laughed.

The two celebs are in town to film an episode of the "Tonight Show," NBC's flagship late-night talk show, at the Detroit Opera House on Sunday night. The special episode will air on Monday, Sept. 15.

Key is a Lions superfan, so his appearance at Ford Field isn't completely uncommon. It's unclear if Fallon is a diehard of any of the NFL's 32 teams, but his cameo alongside Key can be chalked up to the filming.

Through the first 25 minutes of the Lions' game against the Bears, Detroit leads, 21-7.
