An actor and comedian known for "Saturday Night Live" and other television roles was hospitalized Saturday after a traffic collision that killed a fellow comedian. The Los Angeles Times' Show Tracker reports that Tracy Morgan, who was listed in critical condition after being admitted to the hospital, will remain hospitalized for several weeks.

Morgan was one of seven people traveling in a chauffeured limousine that was involved in a deadly multi-car crash on a New Jersey turnpike. Morgan suffered a broken leg, a broken femur, a broken nose and several broken ribs, according to Morgan's publicist, Lewis Kay. One of the passengers in his limo, comedian James McNair, known as "Uncle Jimmy Mack," was killed on impact.

Morgan, 45, was “more responsive” on Sunday, his rep said. He’s at the Robert Wood Johnson University Hospital in Brunswick, N.J., where he had surgery on his leg.

The incident occurred when a tractor-trailer operated by Walmart slammed into the back of the limo around 1 a.m. Saturday, The New York Times notes. Walmart said the driver, Kevin Roper, was an employee of the retailer.

Roper was placed on administrative leave, and was charged with one count of death by auto and four counts of assault by auto, The Times notes. He turned himself in to police at 7 p.m. on Saturday.

McNair, who was 62, has been described as a mentor to Jordan. He and Morgan reportedly became friends after meeting at the Uptown Comedy Club in Harlem when Morgan was just starting his comedy career.

Morgan played Tracy Jordan on "30 Rock" and had his own NBC sitcom, "The Tracy Morgan Show," for one season in 2003-04.
