Tracy Morgan has sued Wal-Mart over last month's highway crash that seriously injured him and killed a fellow comedian.

The former 30 Rock and Saturday Night Live star was released Saturday from a rehabilitation facility as he heals from crash injuries, two days after the lawsuit was filed in U.S. District Court in New Jersey. 

Morgan will continue his recovery at home with an "aggressive outpatient program," spokesman Lewis Kay said.

The lawsuit claims Wal-Mart was negligent when a driver of one of its trucks rammed into Morgan's limousine van. The complaint claims the retail giant should have known the driver had been awake for over 24 hours, and that his commute of 1,125 kilometres from his home in Georgia to work in Delaware was "unreasonable." It also alleges the driver fell asleep at the wheel.

"As a result of Wal-Mart's gross, reckless, wilful, wanton, and intentional conduct, it should be appropriately punished with the imposition of punitive damages," according to the complaint.

The June 7 wreck killed 62-year-old comedian James McNair, who went by the name Jimmy Mack. Comedian Ardley Fuqua and Jeffrey and Krista Millea, who were passengers in the limo, are also named as plaintiffs.

Morgan suffered a broken leg and broken ribs in the crash. Fuqua is recovering from crash-related injuries.

Truck driver Kevin Roper, 35, has pleaded not guilty to death by auto and assault by auto charges. A criminal complaint also accuses him of not sleeping for more than 24 hours before the crash, a violation of New Jersey law.

Roper had been on the job about 13½ hours at the time of the crash, the report concluded. Federal rules permit truck drivers to work up to 14 hours a day, with a maximum of 11 hours behind the wheel.

Morgan's lawsuit seeks a jury trial and punitive and compensatory damages.

A message seeking comment from Wal-Mart was not immediately returned Saturday. An email seeking comment from Morgan's publicist was not immediately answered.
