Although anxiously awaiting medical reports on key personnel, the Brisbane Lions believe they are healthy enough to defy Port Adelaide and win a historic fourth successive AFL premiership.

How forwards Jonathan Brown, Alastair Lynch and Craig McRae recover this week after last night's gruelling preliminary final win over Geelong will be crucial if the Lions are to match Collingwood's 1927-30 feat of winning four straight flags.

Brown (knee) and McRae (hamstring) did not take part in Sunday's recovery session after they were injured in last night's 12.12 (84) to 10.15 (75) win, and the Lions will not know how severe their injuries are until Monday.

Lynch is also in some doubt with calf and quad niggles but is confident he will play.

Veteran midfielder Shaun Hart is the only Lion ruled out of Saturday's decider because of fractures to both cheekbones suffered in a sickening collision with teammate Daniel Bradshaw.

Despite a day's less preparation than Port and the high casualty rate - captain Michael Voss and rover Luke Power were others left bruised and battered - the Lions believe they can overcome the hurdles to reach footballing immortality.

Several Lions spoke of how much the side could improve from the slugfest win over Geelong, while Voss said the injuries were less of a concern than those from grand final week 2003.

Last year Voss, Nigel Lappin, Brown, Lynch and Justin Leppitsch all played hurt against Collingwood.

"I think we were much worse off last year," Voss said.

"We had a lot of guys who were carrying a lot of injuries last year and, to be honest, I don't know how half of them got out there.
