Key forward Daniel McStay could be back to bolster Brisbane's AFL premiership push within a month after scans confirmed some lateral ligament damage in his left ankle.
There were initial fears McStay would be out of action for a longer period when he hurt the ankle during Saturday night's win over West Coast.
But the 26-year-old goal-kicker was cleared of a break and follow-up scans have revealed a sprain.
"He's got a bit of ankle damage there which is an ankle sprain, so we'll give him about three weeks," Lions high performance manager Damian Austin said.
"We'll hopefully get him up and moving by the end of the week."

But Jed Bews is unavailable after suffering concussion in a collision with GWS forward Jesse Hogan.
Melbourne ruckman Max Gawn is in doubt for the match against West Coast after suffering a knee injury.
The in-form Demons captain had scans on Monday after damaging his knee during the round eight win over St Kilda.
"I didn't do much in the second half," Gawn told reporters on Monday.
"I felt a little bit sore in the second quarter but I managed to play out the half and I've woken up pretty good this morning."
Gawn has battled knee issues throughout his career and does not believe the latest issue is a dreaded PCL injury.
"I've had a pretty good start to the year ... and yesterday just got me a little bit in the second quarter," Gawn said.
"But I played out the half, so I'm pretty confident.
"I'll be pushing (to play this week).
"I've woken up really good this morning and I didn't want to do this (MRI scan) today but they said to go in and make sure."
Young star Luke Jackson did most of the ruck work in the second half against St Kilda is capable of playing the lead role for Melbourne if Gawn is ruled out.
