Jay Leno says may need skin grafts after suffering third-degree burns during a scary accident at his garage.

The iconic host of The Tonight Show told TMZ from his hospital bed that he was working on his 1907 White Steam Car over the weekend to fix a clogged fuel line. However, a fuel leak caused gasoline to spray on his face and hands — and almost at the same time, a spark triggered an explosion.

According to TMZ, the explosion lit Leno on fire, but thankfully, his friend Dave was nearby and quickly put out the flames. The incident left Leno with severe third-degree burns on the left side of his face. Leno is expected to be hospitalized for up to 10 days.

On Monday, the former late-night host confirmed to ET that he was hospitalized over the weekend after a gasoline fire at his Los Angeles car garage.

“I got some serious burns from a gasoline fire. I am ok. Just need a week or two to get back on my feet,” he said in a statement.

Speaking with ET, George Swift, an employee at Leno’s garage, explained, “It was a steam car. This steam was made by gas. It got sprayed, as a gas … [Leno] called me and he told me there was a fire and the fire department is coming.”

Swift also said that Leno never lost consciousness during the incident.

“He’s a tough guy. He’s going to be fine. It’s nothing life-threatening. He’s in great spirits. But, you know, it’s going to take awhile… He’s in the burn center. He’s getting the best care,” he said.

News of the accident first emerged when People reported that Leno had cancelled an appearance at a Las Vegas financial conference.

“His family was not able to provide us very many details, but there was a very serious medical emergency that is preventing Jay from traveling,” an email to attendees from conference organizers stated. “All we know is that he is alive, so our prayers go out to him and his family tonight.”

Later, TMZ reported that one of Leno’s cars caught fire, leaving burns on the left side of his face before he was taken to the Grossman Burn Center for treatment.

The outlet also reported that sources said the flames did not affect Leno’s eyes or ear.
