Merrivale key forward Josh Britton is set for a month-long stint on the sidelines after dislocating his knee cap and stretching ligaments in last week's win.
It's a big blow for the fourth-placed Tigers who come up against fifth-placed Allansford in what shapes up as the match of the round.
But the Tigers will be bolstered by the inclusion of star midfielder and former Cat, Leatham Robe.
Allansford has three important additions of its own with Travis Membrey, Jason Wilson and Stephen Kilpatrick back from injury and illness.
The Nirranda and Panmure match is the other one to watch on Saturday.
Blues goal-scoring machine Gary 'The Big Show' Robinson will miss with general soreness.
But ruckman Inoke Ratu is back from holidays and will take pressure off number one ruck Bronte McCann.
Blue Jason Lee has earned his call up after strong performances in the reserves.
Panmure is looking for three on the trot and could give Nirranda a shake.
Hard midfielder Marcus Kelly comes in for his first senior match of the year while Brandon Bant is unavailable.
Old Collegians playing coach Nick Sheehan has a groin injury and will miss his side's encounter with South Rovers.
Star Warrior Josh Dwyer had surgery on his finger early in the week and is set to miss four weeks.
But the Warriors bring in runners Eli Barker, Thomas Lambevski and the versatile Josh Reichman.
South Rovers has made five changes with gun Michael Stacey back for his third match of the season.
Jake Morton, Ben Fary, Abel Farrell and Joshua Moloney are the remaining inclusions.
Russells Creek coach Peter Timms has had to change nearly a third of his team for its Kolora-Noorat clash.
Centre half-forward Liam Antonio has a light hamstring tear but is also going on holidays for the next month.
Midfielder Louis O'Connor sustained a calf injury against Nirranda and will miss.
But the inclusions have Timms upbeat.
Number one ruckman Lukas Essenwanger returns, Caleb Bidmade will provide dash across half-back and former North Warrnambool Eagles player Joe Dwyer is in for his first match of the season.
Young Blair Hewett will also play his first senior match as the substitute.
The Power have maintained a stable line-up but key midfielder Brad Johnson will miss with a knee complaint.
Harry O'Sullivan returns from a shoulder injury alongside young key forward Bailey Kemp.
East Warrnambool coach Danny Chatfield said his group was struggling for numbers with six players unavailable for Saturday.
Ben Hadden and Roy Oakley are among those who have been promoted from the reserves for the Timboon Demons clash.
The Demons have some handy ins.
Leigh McKenzie returns from an ankle injury, Steven Crees is back from the flu and Ewan Flanagan is in for his second match of the season.
