Tracy Morgan is doing better following last weekend's fatal car accident.

In a statement issued Thursday, his rep tells Gossip Cop, "Today was a better day. While Tracy remains in critical, but stable, condition, he continues to show signs of improvement." The spokesperson adds that Tracy's doctors remain "optimistic that his recovery is progressing."

Also the wife of Jeff Millea -- Tracy's assistant who was also hurt in the crash -- says he has "shown much improvement over the past few days."
