Richmond tall forward pair Ty Vickery and Ben Griffiths will undergo concussion tests this week following the Tigers’ first NAB Challenge match against Fremantle last Friday night.

The Club’s Physical Performance Manager Peter Burge said they would both need to tick the necessary boxes before being in the selection mix for Saturday’s NAB Challenge match against Hawthorn at Beaconsfield.

Vickery, who was taken from the ground in the first quarter, would be assessed later this week.

“It’s standard concussion.  He’ll go through the process with the Club doctor and have a concussion test later in the week,” Burge said.

“We take a strong approach to that (concussion), and we have to go through a few hoops before we could consider him to play.”

Burge said Griffiths would follow the same process after copping a heavy knock in the third quarter of last Friday night’s match.

Richmond tall defender David Astbury will be sidelined this Saturday after injuring his thumb during the clash with Fremantle.

“He had some ligament damage and will need minor surgery,” Burge said.

“He’ll definitely miss this weekend, but he should be back pretty soon.”
