Comedian Tracy Morgan still struggling after crash

Nearly three months after being involved in an accident that left a fellow comedian dead, Tracy Morgan may be months away from being able to fully walk again.

Benedict P. Morelli, an attorney for the former "Saturday Night Live" star, said Morgan is "really having a tough time" following the six-car June 7 crash that killed comedian James McNair, The Star-Ledger reported. Morgan's limo bus, in which McNair was traveling, was struck by a Wal-Mart truck.

Morelli said Morgan, who suffered a broken leg, nose and several ribs in the crash, still relies on a wheelchair.

"He's making incremental progress," Morelli said. "But they'll have to wait another month before they assess him cognitively."

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

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