( CNN ) -- Five months after being injured in a deadly limo bus crash , Tracy Morgan is fighting to return to the person he once was , his lawyer said Tuesday . And it seems the `` 30 Rock '' star 's injuries were n't just the broken ribs , broken nose and broken leg that were previously reported . According to attorney Benedict Morelli , the 46-year-old comedic actor also suffered a `` severe brain injury . '' `` Mr. Morgan is a fighter , '' Morelli said , according to NJ.com . `` He 's fighting to get better . And if there 's a chance for him to be back to the Tracy Morgan he once was , he 's going to try to do that . But we just do n't know because of the severity of the injuries that he sustained and the fact that he had such a severe brain injury . '' Police : Driver charged in Tracy Morgan crash was awake 24 hours . On June 7 , Morgan was a passenger on a limo bus that was rear-ended by a Walmart truck on the New Jersey Turnpike . The crash killed Morgan 's friend and fellow comedian James McNair , and left Morgan and his other companions with injuries . As previously reported , a preliminary report by the National Transportation Safety Board showed that the Walmart truck was traveling 20 mph over the speed limit , and that its driver was almost at his drive-time limit . In July , Morgan and three others filed suit against Walmart , stating in a complaint that `` the defendants ' negligence was a substantial contributing factor in causing plaintiffs ' injuries . '' Tracy Morgan sues Walmart over deadly crash . The retailer responded in September by placing part of the blame on Morgan and the other passengers , saying that the injuries sustained were `` caused , in whole or in part , by plaintiffs ' failure to properly wear an appropriate available seat belt restraint device . '' The driver who was operating the Walmart truck , Kevin Roper , has pleaded not guilty to criminal charges that include vehicular homicide and assault by automobile . Tracy Morgan : I ca n't believe Walmart is blaming me . On Tuesday , as representatives for both sides in the lawsuit arrived in court for a scheduling conference , Morelli said that `` the jury is still out '' on whether Morgan will be able to fully recover . `` When you have a traumatic brain injury , it takes a very long time to find out how you 're going to do and how much you 're going to recover , '' Morelli said . `` So that 's where he is . He 's still fighting and trying to live his life at the same time and trying to get better , and he 's just not better . We 're hoping and praying to get him back to where he was . '' Morgan , who spent weeks in the hospital and rehabilitation following the crash , showed gratitude to his fans in September for their continued support . `` I want to thank my fans for sticking with me during this difficult time , '' the `` Saturday Night Live '' veteran said . `` I love you all . I 'm fighting hard every day to get back . ''
