Comedian and actor Tracy Morgan appears to be holding steady after a six-vehicle accident on the New Jersey Turnpike left him critically injured, according to a statement from his publicist. The accident, which occurred at 1 a.m. Saturday when a tractor-trailer slammed into a limo bus carrying Morgan and six others on the northbound lanes of the turnpike as it passes through Cranbury, N.J., resulted in one fatality and four other injuries. The driver of the tractor-trailer, Kevin Roper, 35, has turned himself in after being charged with one count of death by auto and four counts of assault by auto, posting a $50,000 bail.

The status update from Morgan’s rep reads: “While Tracy remains in critical condition, he has been more responsive today, which is an incredibly encouraging sign. He sustained a number of injuries including a broken leg, a broken femur, a broken nose and several broken ribs. He had surgery earlier today on his leg. We expect him to remain in the hospital for several weeks. His family is tremendously overwhelmed and appreciative of the outpouring of love and support from his fans. We will continue to update his status when new information becomes available.”
