Tracy Morgan is still in shock after losing his friend in the car crash, which left him with a number of life-threatening injuries, in New Jersey in June.

The former '30 Rock' star is still trying to get over the shock of losing his friend James 'Jimmy Mack' McNair, 62, in the accident in which a Walmart truck smashed into the limo bus they were passengers in. Fellow comedian Chris Rock, who stars in his new movie 'Top Five' alongside Tracy, told USA Today of his friend: ''He's OK. I saw him not too long ago.

He doesn't live too far from me. I went by his house and showed him a copy of the movie. He was very happy. He's got physical therapists. There's a lot of rehab going on. He's traumatised--his friend died. It's Tracy -- not the most stable guy in the world to begin with.''

The 45-year-old comedian, who suffered brain injuries, a broken femur, broken nose and broken ribs in the accident, is slowly starting to walk again, but it is thought he may never fully recover from the crash.

Tracy's lawyer, Benedict Morelli, said previously: ''He's a bit more mobile. He's able to take some steps and doesn't have to be in a wheelchair every single minute. He's a fighter, but we don't know if he's going to be the old Tracy again.''

Meanwhile, Tracy was extremely upset when Walmart recently accused him in court of being at least partially responsible for his injuries, as the company claims he wasn't wearing a seatbelt when the crash took place. However, the funnyman hit back at the retail giant, insisting ''my friends and I were doing nothing wrong.''

His lawyer said: ''He was so upset. It was all over the place. He was reading about it and seeing in on TV... he replayed to me that he wanted to say something.''
