“I got some serious burns from a gasoline fire,” Leno said in a statement to The Associated Press. “I’m fine. I just need a week or two to get back on my feet.” The cause and time of the fire were not immediately clear. The former “Tonight Show” host is known for his famous car collection, which is housed in a garage in Burbank, north of Los Angeles. Leno, 72, was scheduled to appear at a financial conference in Las Vegas on Sunday but canceled due to a “serious medical emergency,” People magazine reported earlier Monday, citing an email sent to conference attendees. 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 was cool when the show’s ratings fell and brought Leno back as host in 2010 .She stayed on 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 “You Bet Your Life” game.
