While he technically last appeared in the cold opening of ''Rescue Me'', Colasanto's last filmed appearance as Coach was an episode ''Cheerio, Cheers''. When Colasanto died in 1985, Coach was written out as deceased without explanation. Since then, Colasanto's replacement Woody Harrelson joined the cast as Woody Boyd in the fourth season of Cheers.
