Luke Combs performed at Levi’s Stadium over the weekend and brought out a few surprise guests: San Francisco 49ers’ own George Kittle and Brock Purdy. Kittle and Combs pounded beers in front of the crowd. Just three songs later, during the last song of the night, Luke slipped and fell onstage. He played it off like a champ though, and called himself “safe,” like a baseball umpire.
