TRENTON, N.J. (AP) — An attorney for Tracy Morgan says the former "Saturday Night Live" actor is having a tough time recovering from a June accident on the New Jersey Turnpike that left a fellow comedian dead.

Attorney Benedict Morelli tells The Star-Ledger newspaper (http://bit.ly/1sR1Kbk ) that Morgan relies on a wheelchair and it may be months before he can fully walk again. Morelli says Morgan appears to be making progress, but it will be a month before he is assessed "cognitively."

Morgan broke his leg, nose and several ribs in a six-car accident involving his limo bus, and comedian James McNair was killed. The bus was struck by a Wal-Mart truck.

The truck driver has pleaded not guilty to vehicular homicide and assault by auto.

Morgan accused Wal-Mart of negligence in a federal lawsuit.
