AS IF Geelong wasn't scary enough already, star trio Matthew Scarlett, Paul Chapman and Darren Milburn have recovered from injury and are ready to hit September at full steam.

As Sunday's teams were finalised by clubs on Friday evening, Travis Varcoe, Brent Prismall and Ryan Gamble were the unfortunates who made way for them for the round 21 clash with North Melbourne.

The Kangaroos are the other in-form team in the top four, and they've been bolstered by the return of Nathan Thompson at full-forward and star ruckman Hamish McIntosh.

The Roos/Cats clash at Skilled Stadium is clearly the match of the round and could be a preview of week one of the finals. Thompson will play his first game since a knee injury in round 12 – Leigh Brown and Jess Sinclair are the omissions.

St Kilda has named small forward Stephen Milne to take on the Crows in an unchanged line-up from the team that smashed Fremantle last weekend. Milne suffered a cracked cheekbone in Perth – his second in a month – had to be driven home from WA and underwent minor surgery late Thursday morning.

Despite his arduous week he trained strongly on Friday morning at Linen House Oval with the Saints and will take his place.

Adelaide has resisted the urge to rush back Jason Porplyzia despite brain scans showing he has recovered from a heavy knock suffered in round 18. Chris Knights is the only inclusion, replacing the dropped Bruce Campbell.

The West Coast Eagles have regained premiership centre-half forward Ashley Hansen for their final home match of the season. The Eagles take on Hawthorn on Sunday and Hansen is joined in the side by premiership midfielder Sam Butler.

Brett Ebert will miss with general soreness, while Tony Notte is out after playing his debut game.

Hawthorn will travel to Subiaco without two of its regulars, with Luke Hodge (suspension) and Robbie Campbell (virus) to both miss the clash. They've been replaced by Brent Renouf and Clinton Young.
