"I'm such a positive person, I tested positive AGAIN. I am feeling fine - the great John @Mulaney & Andy Samberg @TheLonelyIsland have graciously agreed to host @JimmyKimmelLive for me tomorrow," Kimmel tweeted.
It was just two weeks ago the late-night host announced he couldn't host "Jimmy Kimmel Live!" after testing positive for COVID-19.
John Mulaney and Andy Samberg will host "Live!" Wednesday. A re-run of the show was planned for Tuesday.
Kimmel traveled to New York to appear at the Disney 2022 upfronts on Tuesday but delivered a virtual monologue instead after testing positive.
