A spokesman for Tracy Morgan says the actor and comedian is showing signs of improvement after he was seriously injured in a deadly highway crash in New Jersey last weekend.
Lewis Kay says Morgan remains in critical but stable condition, but his medical team is optimistic his recovery is progressing.
The 45-year-old suffered broken ribs and a broken leg in Saturday's accident on the New Jersey Turnpike.
The crash killed fellow comic James McNair, whose funeral was held on Thursday.
Prosecutors say Wal-Mart driver Kevin Roper's truck hit Morgan's limo.
The Georgia resident has pleaded not guilty to charges of death by auto and assault by auto.
