ST. LOUIS, Mo. – Jay Leno says he’s doing OK after suffering serious burns in a gasoline fire. In a statement to Variety, Leno said he needs a “week or two” to get back on his feet.

Leno was scheduled to perform with Jeff Foxworthy this Friday at the Fabulous Fox Theatre. The venue, and Foxworthy, say that the show is now canceled.

“I hate canceling shows but Jay getting back to health is more important right now”, writes Foxworthy. “Thanks to everyone for the prayers and well wishes. Get well soon buddy!”

The Fox Theatre says that all tickets will be automatically refunded. Ticket holders will receive credit in the next 7-10 days.

The cause and time of the fire wasn’t immediately clear. The former “Tonight Show” host is known for his famed car collection, which is housed at a garage in Burbank, north of Los Angeles.

Leno, 72, had been set to appear at a financial conference in Las Vegas on Sunday but canceled because of a “serious medical emergency,” People magazine reported earlier Monday, citing an email sent to those attending the conference.

The comedian took over NBC’s “Tonight” when longtime host Johnny Carson retired in 1992. Leno was succeeded by Conan O’Brien in 2009, but NBC got cold feet when the show’s ratings dropped and brought Leno back as host in 2010. He remained in the job until Jimmy Fallon took over in 2014.

Leno turned his love of cars into a CNBC series, “Jay Leno’s Garage,” and now hosts a revival of the game show “You Bet Your Life.”
