Tracy Morgan is in critical condition after being involved in a six-vehicle car crash in Cranbury, New Jersey early on Saturday morning.

The 30 Rock star was in a limousine bus with six other passengers on I-95 when the accident occurred, and the other vehicles involved included two tractor-trailers, an SUV and two passenger cars. New Jersey State Police Sgt. Gregory Williams told Fox News that one of the tractor trailers may have rear-ended the limo bus Morgan was in, and though it is still not clear what happened, "drug or alcohol use is not suspected as a cause of the accident."

One person in the same car as Morgan died on the scene, and the actor was transported via helicopter to intensive care unit of Robert Wood Johnson University Hospital. Four other crash victims were brought to the hospital; three were in critical condition and one was in fair condition.

Morgan performed a stand up comedy show on Friday night at Dover Downs Hotel & Casino in Delaware, and his scheduled appearance at the Fillmore Charlotte in North Carolina on Saturday night has been canceled.

Our thoughts are with Tracy and his family.
