AceShowbiz - Jay Leno has undergone a surgery to treat his burn injuries after a gasoline fire this past weekend. Dr. Peter Grossman, medical director at Grossman Burn Center, is treating the comedian and shared that his "condition is good."

Dr. Grossman gave an update on Leno's condition during a press conference on Wednesday, November 16. He said the 72-year-old underwent a surgical excision and grafting procedure to the burned areas to remove unhealthy tissue and place a biological skin substitute on the wounds in order to expedite healing.

"Some of the burns to the face are a little deeper and a little more concerning," the doctor said to the press. He added that Leno is "in good spirits today" and will undergo another procedure later this week.

He added that they have been "very aggressive with hyperbaric oxygen treatment, which can "accelerate burn wound healing by increasing oxygen supply to injured areas and reducing swelling, which is helpful in maintaining healthy blood flow," according to the facility's website.

"Currently, there's no evidence of nerve damage. I do anticipate him making a full recovery. Whether they'll be remnants of this injury, it's still too early to tell," Grossman said, before assuring, "I'd say that his injuries are serious, his condition is good."

The physician went on sharing that while undergoing treatment at the facility, the "Jay Leno's Garage" host has been passing out cookies to children. "We're very happy to have him as part of our team," he joked of the former "Tonight Show" host.

Leno was working on a steam engine underneath a car in his garage on Saturday, November 12 when one of his vehicles burst into flames due to a "fuel leak." He was rescued by close friend Dave, but suffered "significant" burns to his face, chest and hand.

On Monday, he spoke up on his condition in the aftermath of the accident, saying, "I am ok. Just need a week or two to get back on my feet."
