Port Adelaide's Jared Polec is expected to miss around three weeks due to a hamstring injury.
Polec sustained the injury late in the Power's win over the Lions on Saturday evening.
Coach Ken Hinkley said post-match it does not look too serious and will not keep Polec out for too long.
"It looks like a pretty natural hamstring injury and we would suspect, if it is, he would miss two to three weeks," Hinkley said.
"That's just the way it goes in footy.
"We've had an unbelievable run with our conditioning, I'd be a bit tough if I was up here whinging about one hamstring.
"It's footy season, that's what happens.
"We've got good players in good form underneath (in the SANFL), which is really important."
The Power's 40-point win over Brisbane puts them into fourth spot, with seven wins and five losses after 12 rounds.
