Comedian Tracy Morgan may never perform again, as a result of the injuries he sustained in a deadly accident earlier this year, his lawyer has said. The 45-year-old suffered serious injuries in a collision with an allegedly exhausted Walmart truck driver, who slammed into his limo bus on the New Jersey turnpike in June. Fellow comedian James McNair was killed in the crash as he and others were accompanying the former Saturday Night Live-star back from a show in Delaware. Morgan spent several weeks in rehab with rib and leg injuries, but is still undergoing treatment for injuries to his brain, including daily speech, cognitive, vocational and physical therapies. The 30 Rock star’s lawyer, Benedict Morelli, said ‘The jury’s still out’ on whether Morgan will ever be able to perform again.
