Comic Tracy Morgan was "more responsive" Sunday but remained in critical condition a day after a deadly crash on the New Jersey Turnpike, his spokesman said.
Morgan, who starred in 30 Rock and Saturday Night Live, suffered broken leg bones, a broken nose and several broken ribs in the crash that killed fellow comic and Morgan mentor James "Jimmy Mack" McNair, Morgan spokesman Lewis Kay said.
"We expect him to remain in the hospital for several weeks," Kay said. "His family is tremendously overwhelmed and appreciative of the outpouring of love and support from his fans."
State Police said truck driver Kevin Roper, 35, failed to see slow-moving traffic near Cranbury Township. His truck slammed into a 2012 Mercedes limousine-bus carrying Morgan, McNair and several others, setting off a chain-reaction crash involving another tractor-trailer, an SUV and two cars, authorities said.
All the victims were in the limousine. Jeffrey Millea, 36, and comedian Ardie Fuqua Jr., 43, also were listed in critical condition, hospital spokeswoman Zenaida Mendez said Sunday. Comic Harris Stanton was treated and released from the hospital Saturday.
The limousine had been returning from a stand-up comedy show in Delaware. Morgan, 45, was airlifted immediately after the crash to Robert Wood Johnson Medical Center in nearby New Brunswick, N.J.
Roper, 35, was released on $50,000 bail Saturday night, Wal-Mart spokesman David Tovar said Sunday. Roper is charged with one count of death by auto and four counts of assault by auto.
The National Transportation Safety Board said it was investigating. Wal-Mart President Bill Simon said Roper was placed on administrative leave. Simon issued a statement saying the company was "profoundly sorry that one of our trucks was involved." He said Wal-Mart would take full responsibility if it was determined that its truck caused the crash.
Morgan's limo was owned by Atlantic Transportation Services, which issued a statement Saturday extending its "sincerest condolences" to the victims and their families. The firm said it had one employee behind the wheel and a second in the front passenger sea.
"Although the investigation is still pending, we concur with the preliminary reports that the accident was caused by another vehicle traveling behind the Atlantic limo bus," the Rehoboth Beach, Del.-based company said.
Morgan, a New York City native, worked on SNL from 1996 to 2003. He joined the cast of NBC's comedy 30 Rock in 2006, receiving an Emmy nomination for best supporting actor in 2009. McNair, 62, was from Peekskill, N.Y.
