As first hinted in TV Guide magazine, fired Practice star Dylan McDermott is headed back to the ABC drama for a showdown with his successor, James Spader, a show rep now confirms. The actor will reprise his role as legal eagle Bobby Donnell for a two episode arc airing May 2 and 16. "There's a lot of conflict in the office involving Alan," says co-star Camryn Manheim, "so we need our old friend to help resolve it."
