In a statement, Richards said, \"Alex was a legend, revered by all of us. I want to thank our guest hosts, who will not only help all of us celebrate his great legacy, but also bring their own touch to the show.\"

Jennings was the first person to fill in for Alex Trebek, who died last year of pancreatic cancer, and will host six weeks' worth of shows.

A permanent successor for Trebek has yet to be announced.
