Former "Saturday Night Live" and "30 Rock" star Tracy Morgan has been released from a rehabilitation center where he's been recovering from injuries received in a crash involving a Wal-Mart truck that killed a fellow comedian.

"Tracy has been released from the rehabilitation center and will continue his recovery efforts at home with an aggressive outpatient program," Morgan's rep told E! News. "He asked me to pass along his sincerest gratitude to everyone who has helped him get to this point.  He would also appreciate some privacy during this crucial point in his recovery."

Morgan and his entourage were riding in a limo bus on a New Jersey highway June 7 when they were hit by a Wal-Mart truck driven by Kevin Roper, causing a six-vehicle pile-up. The crash killed comedian James McNair, known as Jimmy Mack.

Roper has pleaded not guilty to vehicular homicide charges and four counts of assault by auto.
