The veteran went down halfway through the opening quarter and did not return to the contest for the rest of the night.
And while the club has described the issue as only minor, Cotchin’s availability for the finals is currently unknown.
“It’s disappointing, he’s got a little bit of a tweak. We’re not too sure of the extent of it, but it’s his support leg when he was kicking. We’re hoping it will be on the minor side but once again he’s had the two incidents this year,” Hardwick said post-game.
“It’s disappointing to lose players, and Collingwood lost a couple too, so losing players this time of the year is always tough.”
Hardwick could not confirm whether or not Cotchin would be fit for September.
“I’m not too sure. We don’t know the significance of the injury,” he said.
Cotchin missed two months of football with a hamstring issue earlier in the year then returned for two months before having soreness in the same area.
