Swan Districts could head into this afternoon's top-of-the-table clash at Claremont Oval without their two leading goal kickers, with centre half-forward Tim Geappen in serious doubt because of a knee injury.
A raft of injuries have already forced the league leaders to make five changes in a dramatic shake-up for the showdown.
Spearhead Ashley Hansen, who leads the WAFL's goal-kicking tally with 44 majors, will miss at least a fortnight with another hamstring injury.
He has been joined on the sidelines by first-choice players Wayde Twomey (knee), Tallan Ames (toe) and Brett van Groningen (ankle) as well as youngster Brent Latch (knee).
That situation is likely to be compounded after Geappen failed to train on Thursday night.
Swans coach Greg Harding said 28-year-old Geappen, who has also chipped in with 34 goals this season, had sustained the injury during last Saturday's eight-point loss to West Perth.
"He's probably only a 20 per cent chance to play," Harding said.
"We were pretty lucky early in the season (with injuries), but we've copped them all at one time.
"He's struggling to come up.
"We're going to have to restructure, there's no doubt about that, but Ryan Davis has been in superb form. If we do hold onto (Michael) Walters, he's a class player."
Emergency Aaron McKinlay is on stand-by in case Geappen is ruled out this morning.
The black and whites have been forced to blood two debutants in Ray Daniels and Nathan Broad in a fixture that will determine who holds top spot at the end of the round.
Claremont's situation is a stark contrast. Last year's premiers will welcome back midfielders Jake Murphy and Byron Schammer to significantly strengthen their side.
