The March 4th Saturday Night Live Guest Host is going to be Travis Kelce.
(And I'm sure his brother will show up, too, don't you think?)
It's not unusual to have a sports star as host on occasion. I remember early in it's run in the late 1970's that Fran Tarkenton was a host.

I looked it up: Tarkenton hosted on January 29, 1977.
All sports stars who have hosted SNL; some have hosted more than once:
Bill Russell, O.J. Simpson, Coach John Madden, Bob Uecker, Alex Karras, Mr. T. and Hulk Hogan together, Marvin Hagler, Yankees Manager Billy Martin, Walter Payton with Joe Montana, Carl Weathers, Wayne Gretzky, Chris Evert, Michael Jordan, Charles Barkley (4 times), Nancy Kerrigan, George Foreman, Deion Sanders, Dwayne "The Rock" Johnson (5 times), Derek Jeter, Jonny Mosely, Jeff Gordon, Andy Roddick, Tom Brady, Lance Armstrong (the musical guest was his wife, Sheryl Crow!), Peyton Manning (his brothers Eli and Cooper and his parents also appeared--it was Peyton's birthday), LeBron James, Michael Phelps, Eli Manning, Ronda Rousey, John Cena, J.J. Watt and Travis Kelce.
That's 33 people. May sound like a lot, but SNL has been on 48 Seasons and, to date, 942 episodes!
