Geelong have won four AFLW games in a row for the first time, beating West Coast by nine points to solidify their top-eight berth.
Eagles midfielder Mikayla Western suffered a gruesome-looking injury in the last quarter of the Cats' 4.10 (34) to 4.1 (25) victory.
Western executed a perfect tackle on Claudia Gunjaca late in Saturday's match, but landed awkwardly and her left arm took the impact.
Two trainers helped Western as she walked off the ground giving a thumbs-up, despite having her left arm in a sling.
Eagles coach Michael Prior said Western had sustained an elbow injury and had gone to hospital, but was in good spirits.
"She was pretty happy just before on the green whistle (painkiller)," Prior said.
Only inaccuracy stopped Geelong from enjoying a much more convincing win, with the Eagles hanging tough despite a 17-6 inside-50 count against them.
"I never felt like it was out of our control ... we just didn't make the most of our opportunities," Cats coach Dan Lowther said.
"It's positive that we think we can get better."
The Cats lie fifth with a 6-2 record and face a major test away next Friday night against third-placed Adelaide at Unley Oval.
West Coast won the first clearance of the match and Ella Roberts gave them an ideal start with a quick goal.
But their next did not come until the third term as Geelong took full control.
Livewire Cats midfielder Georgie Prespakis returned from a two-game ban and starred with 21 disposals and 12 tackles.
Amy McDonald, who successfully overturned a one-game ban at the tribunal earlier this week, was also high among the Cats' best.
Nina Morrison had finger surgery last Monday but showed no ill effects, as she racked up 19 disposals.
One of the highlights of the match was the duel between dangerous Cats forward Chloe Scheer and West Coast's Sophie McDonald.
Scheer kicked 1.3 in their entertaining duel, while the Eagles defender was high among her side's best.
When Scheer butchered a shot at goal in the last quarter, hitting the post, McDonald cheekily patted her on the back.
Eagles midfielder Emma Swanson was mighty, with a game-high 24 possessions, but too much of the match was played in Geelong's half of the ground and West Coast were constantly on the back foot.
"They kept us in it a bit, they missed a lot of opportunities," Prior said
"That first half, they had a lot more territory than us and made it really hard for us to score."
