Jack White is stepping in as a last-minute replacement on this week's `Saturday Night Live,` after the NBC show dismissed previously booked artist Morgan Wallen after he ran afoul of COVID-19 guidelines.

White, former frontman of the White Stripes, will make his third solo appearance (and fourth overall, including the White Stripes' appearance in 2002) on `SNL` on Oct. 10, with host Bill Burr. `The White Stripes Greatest Hits` collection will be released Dec. 4.

Country singer Wallen, who was a contestant on `The Voice` Season 6, on Wednesday posted an Instagram video telling fans that he was informed by `SNL` that he would no longer be able to play the show. He said he had not tested positive for COVID-19, but `my actions from this past weekend were pretty short-sighted, and have obviously affected my long-term goals and my dreams.` Wallen was referring to TikTok video posts that showed him socializing in Alabama without a mask at a crowded bar and a house party.

`Saturday Night Live` returned to Studio 8H at 30 Rock (with a limited in-person audience) for the first time since April, when the show moved to an `at-home` remotely produced format amid the COVID-19 pandemic.
