Melbourne youngster Angus Brayshaw will take an indefinite break from football following a fourth concussion in the past 12 months.
Brayshaw's most recent head knock came in the VFL last week and he had already missed two matches due to concussion earlier this season.
He also missed six games last year due to concussion.
Demons skipper, Nathan Jones, told RSN Radio on Tuesday morning, that his young teammate will take a "period of time out", however, he was unable to guarantee a return date for the 21-year-old.
"I caught up with Angus last week and he's having a small period away from the club, just to recover from his latest head knock," Jones said.
"I think he'll probably take a period of time out of the game, as long as that is I'm not too sure at this stage.
"I guess there's a process of getting tests and seeing how he's progressing with the normal SCAT (concussion) testing and whether that testing goes to another level.
"We expect (him) to getting back playing again."
Despite impressing in his short career to date and being touted as a future star of the competition, Brayshaw has managed just 33 AFL games since being selected with pick No.3 in the 2014 National Draft.
However, Jones said Brayshaw is in positive spirits despite the setback.
"He's got a really positive mindset about it and wants to get some luck back," Jones said.
"I think he'll be right, but obviously (it's) a tough time for him trying to work through the whole process and where it sits with all the media hype around concussion, which is an interesting debate in itself.
"I think 'Gussy' will be fine and he'll be back again better than ever."
