Prismall, 26, was delisted by the Bombers at the end of the 2012 season, his body having consistently crumbled under the pressures of the unforgiving AFL lifestyle.
The former Cat looked to have been thrown a lifeline by the Bulldogs, though, when he was invited to train at Whitten Oval prior to the pre-season and rookie drafts.
But, the unlucky midfielder was overlooked in favour of Dogs home-grown rookie and player welfare manager Brett Goodes.
In an interesting twist, Prismall was then offered the job at the Bulldogs left vacant by Goodes, the brother of evergreen Sydney champion Adam.
While happy with his new role for this year, Prismall has refused to rule out a possible comeback to AFL in seasons to come.
"I'm not ruling it out, but at the same time I'll see what happens," Prismall told SEN on Tuesday.
"If there was something that opened up, like most other blokes who've gone out of the system, I'd certainly look at it."
Prismall played 36 games over three seasons at Essendon, but managed none last year as he clawed his way back from a second knee reconstruction.
Prismall, who also made 25 appearances over three frustrating years at Geelong, said he welcomed the new challenges of seeing the AFL world from another perspective.
"(My career) obviously finished a little bit earlier than what I would have liked, but I certainly don't shut the door.
"By the same token, I'm really excited by this job. It's something I can do for a long time."
Prismall said his experience as one of the game's hard-luck stories made him better able to fill the role as Dogs welfare manager.
"The average AFL career is about four-and-a-half years so it's not a long period of time in the game," he explained.
"My job is to best prepare them to move out of the game.
"We don't like having those conversations with players but the reality is players are going to go out of the system at 22 or 23 years old.
"A lot of their other mates who have gone through school have a degree and are starting work.
"So going out of (the AFL) they can be a little bit behind the eight ball. We prepare them for that."
