Tracy Morgan is improving after the car accident that left him in critical condition, according to a statement issued Thursday by his rep Lewis Kay.

“Today was a better day,” the statement reads. “While Tracy remains in critical, but stable, condition, he continues to show signs of improvement. His medical team remains optimistic that his recovery is progressing.  Megan remains by his side and is relaying the countless good wishes and prayers that his family, friends and fans have been sending their way.”

The statement also included an update on Morgan’s assistant, 36-year-old Jeff Millea, who was injured in the accident as well:

“In addition, Jeff’s wife asked us to pass along that Jeff has also shown much improvement over the past few days.  She is very thankful for the love and support she and their family continue to receive.”

Morgan and Millea are two of the seven people who were in Morgan’s limo when a truck, driven by Kevin Roper, struck its rear early Saturday in New Jersey. Comedian Jimmy McNair was killed in the crash, while Morgan, Millea and two others were injured. Roper has been charged with vehicular homicide and assault by auto.

Roper was reportedly dozing at the wheel while driving a Walmart truck and failed to notice slow traffic ahead. He then hit the limo, causing it to lose control and overturn.

Roper pleaded not guilty to the charges during an arraignment on Wednesday. If convicted on all charges, he reportedly faces up to 15 years in prison.

Morgan’s family denied rumors on Monday that Morgan’s leg was being amputated. The comedian had surgery for a broken leg on Sunday. His other injuries include a broken nose, broken ribs and a broken femur. He’s expected to remain hospitalized for weeks, currently at the Robert Wood Johnson University Hospital in New Brunswick, N.J..

Footage of the horrific crash scene surfaced online via TMZ, shot by a passerby. It allegedly shows comedian Ardie Fuqua being lifted out of the wreckage, unconscious, and placed onto the freeway. In response, Louis C.K. has requested that the gossip site remove the video.

“Take it down TMZ,” he wrote on Twitter. “Now. Please.”

“(Artie’s) brave daughter has asked them to take it down,” he also wrote. “They won’t.”

TMZ has yet to remove the footage.

On Tuesday, FXX confirmed that it plans to keep Morgan’s new comedy series in its slate.
