Banged-up Brisbane will likely be without star Lachie Neale for the rest of the finals as they attempt to defend their premiership.
The dual Brownlow medallist injured his right calf in the Lions' 16.16 (112) to 11.8 (74) qualifying final defeat to Geelong at the MCG on Friday night.
It was Neale's first game in more than a month, having been sidelined for the last three games of the home-and-away season due to a quad complaint.
Lions coach Chris Fagan admitted he was "not expecting great news" from Neale's scans
"Looks like he's done a calf, so that's not a good thing," Fagan said.
"He's a pretty tough sort of guy, can usually play through those, but he couldn't.
"It takes a lot for him to come off, so I'd suspect it's something significant."
Neale still gathered 32 disposals again
