Two days after Tracy Morgan was involved in a fatal six-car crashed that killed one and injured several passengers, the former SNL actor remains in critical condition but appears to be showing signs of improvement, according to Morgan’s publicist, Lewis Kay.

"While Tracy remains in critical condition, he has been more responsive today, which is an incredibly encouraging sign," Kay said. "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."

According to Sgt. Gregory Williams of New Jersey State Police, Morgan’s limo van was hit by a truck on the New Jersey Turnpike at 1 a.m. on Saturday.

The wreck, which killed Morgan's passenger, comedian James McNair, also injured several others, according to officials.
