Sydney ruckman Shane Mumford will return from a knee injury for Sunday's testing AFL clash with Carlton at Etihad Stadium.

Fellow big man Mark Seaby kept his spot, after a strong performance in last round's win over Richmond, with forward Trent Dennis-Lane the player dropped.

Swans coach John Longmire was confident the return of Mumford, alongside Seaby and Lewis Roberts-Thomson, who has helped out in the ruck in Mumford's absence, would not create an imbalance.

"What we are confident in is that the players we have got are really versatile," Longmire said.

The Blues included half-forward Ryan Houlihan for his first game this season, replacing defender Paul Bower.

Fremantle midfielder Michael Barlow will make his long-awaited AFL return, 11 months after badly breaking his leg in round 14 last year to abruptly halt his stunning debut season.

The Dockers will also give elevated rookie-lister Ben Bucovaz an AFL debut against Melbourne at the MCG on Sunday.

Midfielder David Mundy (leg) and forward Hayden Ballantyne (hamstring) are out injured.

The Demons regained key defender Colin Garland and recalled forward Ricky Petterd, while losing Neville Jetta (hand) and dropping Michael Evans.

Port Adelaide regained captain Domenic Cassisi for Sunday's Patersons Stadium meeting with West Coast.

It will be the skipper's first game since fracturing his leg in round two.

Daniel Stewart also returns for the Power, with Jacob Stewart and Andrew Moore both dropped.

The Eagles made one change, Tom Swift replacing Chris Masten.
