The comedian Tracy Morgan, who was gravely injured in a crash more than a week ago, has been upgraded to fair condition, his publicist said on Monday, calling it a “great improvement.”

Mr. Morgan, 45, a former cast member of “Saturday Night Live” and “30 Rock,” had been in critical condition after a six-vehicle accident on the New Jersey Turnpike on June 7. He sustained several injuries, including a broken leg, a broken nose and several broken ribs.

“His personality is certainly starting to come back as well,” his publicist, Lewis Kay, said in a statement.

Mr. Morgan was injured when a Walmart truck slammed into the back of the luxury van in which he was a passenger as he was returning to New York City from a comedy show in Delaware. Another comedian, James McNair, known as Jimmy Mack, died in the crash, and two other comedians and Mr. Morgan’s assistant, Jeff Millea, were also injured.
