Tigers youngster Jack Higgins has been sent to hospital with a brain bleed.
The 20-year old was experiencing headaches on Monday and was admitted to hospital the following day, with scans revealing the bleed.
He is still in hospital, but the Tigers believe he did not suffer any sort of head knock while playing in the VFL on the weekend.
The Age’s Daniel Cherny broke the story, who could not confirm the extent of the problem while speaking on SEN’s The Sporting Capital.
“Richmond’s Jack Higgins was hospitalised I believe today, he’s certainly in hospital tonight with a brain bleed,” Cherny said.
“There’s quite a bit of uncertainty about this, he was suffering some headaches and he had scans and it’s been revealed to be a brain bleed which is obviously inherently serious, any brain bleed is serious.
“Just how serious it is remains to be seen. The club’s not sure how it’s happened so there’s a fair bit of uncertainty around this and more to play out here.
“As I understand they don’t think it’s related to any head knock or Richmond aren’t aware of any head knock he’s suffered that has led to this, so it is a bit of a mystery in that sense.”
It is unlikely that he will play again this season, with the club set to release a statement with further information later on Wednesday.
