FREMANTLE will unveils its second debutant of the season with Lachie Weller one of three inclusions to the face Greater Western Sydney at Domain Stadium on Sunday.

Weller, who was taken with pick 13 in last year's NAB AFL draft, is the younger brother of St Kilda's Maverick Weller and looks an exciting midfield prospect.

Nat Fyfe is out with a groin issue that coach Ross Lyon hopes is only a one-week injury, while Matt Taberner and Clancee Pearce, who partially dislocated his shoulder last week against Richmond, have been omitted.

Zac Dawson has been named for his first game of the season after two matches in the WAFL and Tendai Mzungu has been included for just his fourth game of the year.

Meanwhile, the Giants have made five changes with four of them forced. Nick Haynes (groin), Devon Smith (knee), Rhys Palmer (hamstring) and Zac Williams (hamstring) are out, while Curtly Hampton has been omitted.

Giants co-captain Phil Davis is back after six weeks out with an ankle injury and

Nathan Wilson, James Stewart, Matt Buntine and Will Hoskin-Elliot are also included for the trip to Perth.

Essendon has lost key defender Michael Hurley to a knee injury for the clash against the Western Bulldogs at Etihad Stadium.

Jake Carlisle returns from injury, along with Jake Melksham, Adam Cooney and ruckman Jonathan Giles for his Bombers debut.

Ben Howlett and Shaun Edwards have been omitted along with big man Shaun McKernan.

The Bulldogs have named an unchanged line-up following their impressive win over Collingwood last week with Tom Boyd to spend another week in the VFL.

Port Adelaide has dropped Angus Monfries and Jarmey Impey for the clash with St Kilda at Adelaide Oval.

Dashing defender Jasper Pittard returns from an ankle injury and Sam Gray has also been included after 31 possessions in the SANFL.

The Saints' side has taken a hit with Nick Riewoldt (calf), Sam Gilbert (thigh/groin) and Jack Lonie (rested) out.

Tim Membrey, Tom Hickey, and Daniel McKenzie are back into the side, but doubts remain over David Armitage after the star midfielder missed training on Thursday.
