Actor and comedian Tracy Morgan remains in critical condition after a six-car accident that took place early Saturday morning.

“His family is now with him and he is receiving excellent care,” Morgan’s rep tells EW in a statement. “We will provide a further update once more information becomes available.”

The accident occurred around 1 a.m. on the New Jersey Turnpike, Sgt. Gregory Williams of New Jersey State Police told the Associated Press. Morgan was traveling with six others in a limo bus that overturned in a collision. “The limo bus is the only vehicle that overturned,” Williams said. “Looks like one of the tractor-trailers may have rear-ended that limo bus, but that’s preliminary at this time.”

AP reports that in addition to the limo bus, two tractor-trailers, an SUV and two cars were also involved in the accident. A spokesman for the Robert Wood Johnson University Hospital said four patients are being treated there — three are in critical condition and one is in fair condition. Authorities confirmed that one man, comedian James McNair, who goes by the stage name Jimmy Mack, died in the crash. Comedians Harris Stanton and Ardie Fuqua were reportedly also passengers in the limo bus.

The 45-year-old Morgan, who starred in 30 Rock and Saturday Night Live, performed at Dover Downs Hotel & Casino in Dover, Del., on Friday night.
