The 30 Rock star suffered a broken femur, a broken nose and several broken ribs when the limo bus he was travelling in was rear-ended by a truck, and flipped.Four other vehicles were also involved in the accident, which cost Morgan's comedy writer pal James 'Jimmy Mack' McNair his life, and left Morgan, his assistant Jeff Millea and fellow funnyman Ardie Fuqua in critical condition.Another passenger is said to be in fair condition.Morgan headed into the operating room on Sunday to have surgery on his injured leg and he is currently in recovery.He remains in intensive care, but his representative has said the 45-year-old is gradually becoming more responsive.The spokesperson added: "His family is tremendously overwhelmed and appreciative of the outpouring of love and support from his fans."The actor, who is facing a long recovery period, was on his way home after performing a stand-up gig with Fuqua in Delaware on Friday night.Truck driver Kevin Roper has since been charged with one count of death by auto and four charges of assault by auto. He was released on $50,000 (£31,250) bail on Saturday night.Meanwhile, the driver of Morgan's limousine has spoken of his horror at seeing his passengers trapped in the twisted wreck after the crash.Tyrone Gale told the New York Daily News: "I climbed around and heard Tracy screaming for help. I climbed up on the body of the limo bus... but I couldn't reach them...I just remember the impact. "We didn't know which way was up, which way was down. I don't know if we flipped several times or one time. "I saw the condition of everybody, and I knew it would just make it worse if I tried to pull them up and out of the vehicle."
