The call to delist the trio came hours after the Dogs formally big farewell to assistant coach and premiership winning Cat, Travis Varcoe.
Within a statement released by the Whitten Oval team, Bulldogs list boss Sam Power wished to thank each of O'Brien, Raak and McComb for their respective services to the club.
“We appreciate the dedication and commitment from Tim, Cody and Robbie during their time at the Club and wish them all the best for their future endeavours,” Power said.
“They are terrific people who will always be welcome back at VU Whitten Oval.”
The trifecta now joins former Demon Mitch Hannan in heading for the exits, as well as ex-Giant and Saint Josh Bruce who hung up the boots after re-repturing his ACL during the final month of the season.
The Bulldogs will enter the upcoming draft holding picks 10, 17, 36, 63, 66 and 84.
