Shane Mumford back to boost Swans against Fremantle Sydney ruckman Shane Mumford returns from injury in time to face Fremantle on Saturday night. THE Sydney Swans have been boosted by the return of ruckman Shane Mumford for tomorrow night's vital match against Fremantle at the SCG. Mumford was a late withdrawal with groin soreness from the team which was soundly beaten by Hawthorn at the MCG last week. The Dockers' ruck stocks have been decimated by injury, with Aaron Sandilands, Jonathon Griffin and Kepler Bradley all out of action. "There was a bit of a question mark on him earlier in the week on Monday and Tuesday, but he ran on Tuesday and ran really well, and then trained today and did all he needed to do and pulled up really well," Swans coach John Longmire said. The Swans are likely to have a huge size advantage in the ruck because both Mumford and the in-form Mike Pyke are playing. The Dockers are expected to use defender Zac Dawson in the ruck. Also coming into the Swans team are premiership player Mitch Morton and Irishman Tommy Walsh for his first game of the year. Tony Armstrong, Jed Lamb and Jesse White have all been omitted. The Giants have made four changes for their match against Hawthorn in Launceston. Mark Whiley, Tim Golds, Anthony Miles, Tomas Bugg come in for Sam Reid, Adam Treloar, Jacob Townsend (calf) and Zac Williams (ankle).
