Morgan's agent released a statement Friday that said Morgan is expected to remain in the facility for "the next few weeks. While he is continuing to show signs of improvement, he still has a long way to go," the statement said.
Morgan's mentor, James McNair, was killed when a tractor-trailer slammed into a limo van carrying the comedians on June 7. Two others, along with Morgan, were critically injured.
New Jersey prosecutors have charged the tractor-trailer driver, Kevin Roper, with vehicular homicide and assault.
