Morgan, 45, suffered injuries including a broken leg, a broken femur, a broken nose, and broken ribs; he had surgery on his leg yesterday. He'll likely remain in a New Jersey hospital for "several weeks," the statement says. Meanwhile, authorities revealed today that Kevin Roper, the Walmart truck driver who hit Morgan's chauffeured SUV limousine, hadn't slept for more than 24 hours before the accident, the New York Post reports. The tractor-trailer "failed to observe slow-moving traffic ahead of him," overturning Morgan's limo and then causing a "chain reaction" with the other vehicles, according to a police officer. An onlooker tells People she saw the truck swerve, and Morgan's limo spin and ultimately flip after being hit. "It was a horrific sight," she says. The limo driver, who was not seriously hurt, says he heard Morgan calling for help after the wreck, according to the Hollywood Reporter. Roper, 35, has been charged with death by auto and assault by auto. The New York Daily News notes that Roper's Twitter bio used to say, "Driving trucks for a living it’s my road move or get hit! #Walmart." It has since been changed slightly. Walmart claims Roper doesn't have a Twitter account, but a friend of Roper's says the account is indeed Roper's.
