Tracy Morgan suffered a debilitating brain injury in the deadly June limo crash he survived — and his career could be in jeopardy, his lawyer revealed Tuesday night.

The 45-year-old funnyman is undergoing rigorous rehab including daily speech, cognitive, vocational and physical therapies in an attempt to get his life back since the New Jersey accident left him wheelchair-bound.

When asked if the “30 Rock” comic will ever perform again, his lawyer, Benedict Morelli, said, “The jury’s still out.”

“The doctors don’t know the answer. I don’t know the answer,” he added.

Morgan was heading back from a stand-up show at a Delaware casino June 7 when a tractor-trailer smashed into his stopped limo at 65 miles an hour, killing fellow comedian James “Jimmy Mack” McNair and leaving Morgan and two of his friends with critical injuries.

Morelli eviscerated the retail giant after it blamed the comedian and his friends Monday in court for not wearing their seatbelts, a “disregard of [their] own interests.”

“These people are despicable,” said Morelli, who is representing both Morgan and two of his fellow passengers, Jeffrey Millea and Ardie Fuqua, in a federal lawsuit filed in July. “They knew that they changed these people’s lives forever and killed somebody.”

Walmart’s arguments infuriated Morelli, who added, “They’re good blame shifters. I guess that’s how they make $783 billion a year, shifting the blame.”

But Morelli is more distressed about his client, who also denounced Walmart’s court arguments Tuesday in a powerful statement.

“After I heard what Walmart said in court I felt I had to speak out,” Morgan said in a statement. “I can’t believe Walmart is blaming me for an accident that they caused.”

“My friends and I were doing nothing wrong,” Morgan continued. “I want to thank my fans for sticking with me during this difficult time.”

Fuqua, who opened for Morgan the night of the crash, suffered serious injuries and is scheduled for surgery tomorrow. Morgan may have more surgeries in his future, too.

Morelli said the three survivors’ memories of the crash are fuzzy, saying, “When you have a traumatic brain injury, you remember certain aspects. This isn’t unusual — it wipes away certain thoughts.”

The accident has also cost Morgan numerous jobs including a TV show and a movie, Morelli said. But he is doing everything he can to make a comeback.

“I love you all,” Morgan added. “I’m fighting hard every day to get back.”
