AFL.com.au's Michael Whiting explores the possible changes to our QClash winning side.

It's going to be hard to change a winning team, but a couple of standout first-year players could be putting their hand up for a run on the MCG on Sunday against Melbourne. 

Alex Witherden (hamstring) and Jarrod Berry (foot) both missed Saturday's big win over Gold Coast but are expected to be right in the frame to take on the Dees at the home of football. 

If the duo are right to go, who they replace will be the next question. 

Claye Beams - who replaced Berry on the weekend - was strong in his return to the Senior side, collecting 15 disposals and kicking a goal. 

Melbourne has plenty of selection decisions this week. AFL.com.au's Ben Guthrie investigates. 

With finals on its radar, Melbourne will start to settle on its best 22 in the coming weeks.

But, as coach Simon Goodwin said, selection decisions will be based on form. So Jack Watts and Sam Frost are no certainties to return to the side after a rejigged forward line and new-look defence performed strongly against the Saints. 

Watts had 22 disposals and kicked one goal in an encouraging VFL effort, while Frost was the carryover emergency along with midfielder Corey Maynard.

Despite collecting 28 disposals in the VFL at the weekend, Christian Salem will be unavailable for selection after accepting a one-match suspension for striking Carlton's Liam Sumner.

In better news, star forward Jesse Hogan has been thrust into the selection mix and is a chance to return earlier than expected from a broken collarbone. However, much will depend on how he trains in full contact drills on Wednesday and Friday. 

Billy Stretch (29 disposals) and rookie Declan Keilty (22 disposals and 11 marks) were Casey's strongest performers on the weekend and will be considered. Tom Bugg has served his six-week suspension for striking Sydney's Callum Mills but will return via the VFL.
