(CNN) -- One of the comedians who was riding in the limo bus with Tracy Morgan during a fatal accident this weekend says the actor ended up unconscious on top of him after the wreck, CNN affiliate WABC reported Tuesday night.
The station spoke with Harris Stanton, the only one of the five survivors from the limo who has been released from the hospital.
The collision killed comedian James McNair, who performed under the name Jimmy Mack, and injured four others on the bus. Morgan suffered broken ribs, a broken nose and a broken leg.
Stanton didn't realize the van had flipped after it was hit early Saturday on the New Jersey Turnpike. He asked a WABC reporter how many times the limo rolled.
He said he was sitting facing Morgan when the accident occurred, which blindsided them because the van had no windows where they were seated.
"When it stopped, Tracy was on top of me and I didn't see anyone else," Stanton said. "I was just saying, 'help me, get me out of here.'"
Morgan moaned but never appeared to be conscious, he said.
Stanton sustained a broken wrist and a bruised ankle.
A fiancee's plea
Morgan's fiancee, Megan Wollover, asked fans Tuesday to stop speculating about his health after false rumors that he could lose his leg surfaced.
"The concern for his well-being has been overwhelming, but Megan is respectfully asking that the media await official word through these channels before speculating (mostly inaccurately) on his condition," Morgan's publicist, Lewis Kay, said in a statement. "Rumors about amputating his leg are completely fabricated."
Morgan underwent surgery for his broken leg Sunday and is likely to remain hospitalized for several weeks, Kay said Monday. There was no change in his condition -- critical but stable -- on Tuesday, Kay said.
"This recovery will be arduous and we hope that you can be patient during this difficult time," Kay said in an earlier statement.
Comedian Ardie Fuqua and Jeffrey Millea were also injured in the accident.
The truck driver who police say caused the accident has been charged with vehicular homicide and assault by auto.
According to a criminal complaint, Kevin Roper, 35, had been awake for more than 24 hours at the time of the crash. He failed to notice traffic slowing in front of him and hit Morgan's bus despite trying to swerve out of the way, police said.
Roper, a driver for Walmart, posted $50,000 bond and was released from jail Saturday night.
Walmart said in a statement that it believed Roper was operating within federal rest guidelines, but said it would take full responsibility should the investigation show its truck caused the accident.
Morgan, 45, was a regular on "Saturday Night Live" for seven years. He later received an Emmy nomination for his role in the comedy series "30 Rock," in which he played Tracy Jordan, an exaggerated version of himself.
