Ross Lyon defends Aaron Sandilands' late inclusion after Damien Hardwick questions the move.
Sandilands was named as an emergency after not having played since round 11. He was then a late inclusion in the game against Richmond after Jon Griffin "tweaked his groin" in the final on-ground warm-up and was withdrawn 10 minutes before the opening bounce.
"Look, that's within the rules. Whether it's in the spirit of the game, I don't know. That's for you guys (media) to find out," Hardwick said.
"You prepare one way and then all of a sudden, something happens and you've got to start preparing another way."
Lyon challenged anyone to provide evidence of Griffin's injury not being genuine.
I'm on record here, this is bona fide and legitimate, and if anyone wants [to make] accusations outside of that they're well and truly out of line and want to be really careful," Lyon said.
"There is no ruse here. If anyone is calling us liars, they'd want to be really strong and have strong evidence."
