Dr. Mark Greene is coming back to "ER," but he's not coming back from the dead.

Anthony Edwards will reprise the role of Greene, who died of a brain tumor at the end of the 2002 season, in flashback scenes in the Nov. 13 episode, NBC announced Thursday.

Dr. Greene will be shown with other characters from the show's past and during an encounter with series newcomer Dr. Cate Banfield (Angela Bassett). The new season premieres Sept. 25.
