Senior coach Chris Fagan has stuck with the same side that dismantled Collingwood by 85 points at the Gabba in Round 22.
However key defender Marcus Adams has been added to the list of emergencies after training strongly this week.
Adams has not played since developing a stress reaction in his foot following the Round 17 loss to St Kilda at Metricon Stadium.
Veteran wingman Mitch Robinson will spend another week rehabilitating a calf injury.
With Port scheduled to play the Western Bulldogs on Friday night, the Lions will know by gameday whether they are a chance to push into the top four.
In form goal kicker Charlie Cameron said while the second chance a top four finish provides would be nice, of greater importance to the Lions was heading into the finals in good form.
He said the side would approach Saturday’s clash in the exact same manner regardless of the result on Friday night.
The key to the blistering for over the past two weeks has been the energy among the playing group and Cameron said a focus would be on starting the game with a bang.
“It doesn’t matter where we finish, we want to finish the year well and gear ourselves up for finals,’’ he said.
“They (West Coast) look dangerous on paper, and we have got to respect that.
“We want to try and ambush them in the first quarter, we want to bring that pressure and energy for the contest and get the ball going forward.
“That’s the key I reckon, that energy.’’
