Graham said he knew his fate once he spoke to Tigers coach Damien Hardwick before the team's main training session in the lead-up to the match.
"I knew once he grabbed me. I thought, 'this can't be good'. We hadn't even had the main session yet. "It was hard to swallow," Graham said.
"But, at the same time, if there's a bloke who is 100 percent fit and I'm going to be 90 percent fit … I'd have still given everything I could have with that 90 percent, but it would have been silly to pick me and not the fit person."
