The comedian and “30 Rock” star has been recovering from a traumatic brain injury after a June 2014 car wreck on the New Jersey Turnpike.

Many experts believed his recovery would be complicated by the fact that he’s living  diabetes.

The Daily Beast says it’s a testament to the remarkable and also unlikely success of his treatment and recovery that, after such a traumatic brain injury and bleak initial prognosis, he will be well enough to go live from Studio 8H just two months from now. “It’s a miracle, really,” Dr. Brian Greenwald, Morgan’s brain doctor, tells The Daily Beast.

Dr. Greenwald is the medical director at the JFK Johnson Rehabilitation Institute in Edison, New Jersey, where Morgan was brought two weeks after the June 7 crash last year. He was in a coma at the time and treated for over a month in the rehabilitation center before continuing his recovery at home.

And Dr. Greenwald has been seeing Morgan once a month for the past year.

“When I started treating Tracy in June 2014, if someone had told me that he’d be on SNL in October of 2015 I would’ve had to look at that with great doubt,” he says. “Unfortunately, so many people don’t recover as well as he does.” Then that word again. “He’s really nothing short of a miracle in general.”

Morgan was traveling from a comedy gig in Delaware when the limousine van he was riding in collided with a Wal-Mart truck on the New Jersey Turnpike, leaving him with a serious brain injury, a broken leg, and broken ribs. He and the crash’s other victims reached a confidential settlement with Wal-Mart in May; a separate wrongful death claim had already been settled with McNair’s children in January.

Recently Morgan described to Today show host Matt Lauer what had been a long and arduous recovery process.

“There are times when I have my good days and my bad days,” he said at the time, holding a cane to walk and pointing out scars on his forehead. “I’ll forget things. There are times when I get headaches and nosebleeds, and I won’t even let my lady know because I don’t want her to be worried about it.”

Morgan is still very much in the recovery stage, Dr. Greenwald also confirms, reiterating that Morgan himself says that he still doesn’t feel fully back to normal. But he is also not concerned that taking on a task as potentially grueling and taxing as hosting SNL won’t slow or endanger Morgan’s recovery.

“There’s obviously some risk when you’re taking on something so intense like this,” Dr. Greenwald says. “I think based on where he is in his recovery, though, it’s certainly not unreasonable to try.”
