Actor and comedian Tracy Morgan was in critical condition Sunday after suffering injuries, including a broken leg and nose as well as several broken ribs, in a deadly New Jersey highway crash. Comedian James McNair, 62, known by his stage name Jimmy Mack, was killed.

Morgan is one of America's best-known black comedians, using humor to spotlight racial prejudices. He is most famous for the "30 Rock" and "Saturday Night Live" television shows.

The comics were returning from a performance in Delaware around 1 a.m. on Saturday when a truck slammed into the back of their chauffeured Mercedes limo bus in New Jersey, flipping it over. Another truck and three cars then plowed into the vehicles.
