When is Aaron Rodgers hosting 'Jeopardy!'? Full 2021 guest host schedule, episodes featuring Packers QB Vinnie Iyer "Jeopardy!" is doing its best to live up to the great legacy of late host Alex Trebek. The producers of the iconic American answer-and-question general knowledge game show have lined up an eclectic group of notable guest hosts to take their turns at the lectern over the next few months, with several more to come. Ken Jennings, who won "The Greatest of All Time" tournament last year to stamp his status as the best all-around "Jeopardy!" player ever was first up helping to replace Trebek during the show's just completed run of episodes. Packers quarterback Aaron Rodgers, once a winning contestant on the celebrity edition in 2015, also will get his chance to be on the other side and read clues.
