THE WESTERN Bulldogs have dropped young forward Tom Boyd for their crucial clash with Collingwood at Etihad Stadium on Sunday.

Boyd has kicked just one goal in his last three matches after kicking four against the Brisbane Lions in round 12 and is the only casualty from the Bulldogs' loss to Geelong last week. 

Ex-Swan Shane Biggs comes into the side for just his third game of the season.

Collingwood has recalled Tyson Goldsack as the replacement for injured star Travis Cloke. Goldsack returns after missing the last three matches with knee tendinitis.

West Coast has turned to second-year tall Tom Barrass to replace key defender Jeremy McGovern, who will miss Sunday's clash against the Sydney Swans with a hamstring injury.

Barrass, a 194cm defender from Claremont, will make his debut after starting the year in the WAFL reserves. He was drafted with pick No.43 in the 2013 NAB AFL draft.

The Swans have replaced suspended defender Ted Richards with his young brother Xavier, who comes in for just his second career game.

Ruckman Mike Pyke returns from a knee injury, while young star Isaac Heeney has been included after three games in the NEAFL, including a 29-possession game at the weekend.

Jeremy Laidler also returns, while Brandon Jack is the only omission with Ted Richards (suspension), Kurt Tippett (hand) and Craig Bird (calf) all unavailable.

St Kilda has dropped veteran Farren Ray for Sunday's clash with Melbourne with Adam Schneider recalled after missing last week.

Experienced Melbourne defender Jack Grimes returns after impressing in his second VFL game back from a broken thumb last week.

Viv Michie has also been included with Jay Kennedy-Harris and Alex Neal-Bullen both omitted.
