Wallabies plan to steamroll Lions with extra forwards on bench Wallabies captain James Horwill, centre, and team-mates at training in Sydney. Robbie Deans is set to go for extra forward firepower on the bench in Saturday's decider. WALLABIES coach Robbie Deans appears set to gamble on a six/two split between forwards and backs on the reserves' bench for the deciding third Test against the British and Irish Lions in Sydney on Saturday night. The expected inclusion of backrower Ben McCalman in the Wallabies' 23-man squad is a strong indication Deans intends to stack the bench with forwards after the Lions won the battle of the breakdown in the second Test in Melbourne last Saturday night. McCalman, who has not played a Test since the Wallabies' win against Wales in Cardiff at the end of 2011 and was called into the squad as an injury replacement, will provide cover for blindside flanker and number eight, but not openside flanker or second row. This means Deans must still decide between veteran openside George Smith and rising number seven Liam Gill as the back-up to Michael Hooper. Gill played well off the bench in the first two Tests, but Smith is now available for selection after recovering from a knee injury. Halfback Nick Phipps and fullback Jesse Mogg are expected to be the only backs on the bench. It is unlikely there will be any changes to the side that ran on for the Wallabies' series-levelling 16-15 win in Melbourne. Possible Wallabies team: 15: Kurtley Beale, 14: Israel Folau, 13: Adam Ashley-Cooper, 12: Christian Lealiifano, 11: Joe Tomane, 10: James O'Connor, 9: Will Genia, 8: Wycliff Palu, 7: Michael Hooper, 6: Ben Mowen, 5: James Horwill (c), 4: Kane Douglas, 3: Ben Alexander, 2: Stephen Moore, 1: Ben Robinson. Reserves. 16: Saia Faingaa, 17, Sekope Kepu, 18: James Slipper, 19: Rob Simmons, 20: Ben McCalman, 21: Liam Gill or George Smith, 22: Nick Phipps, 23: Jesse Mogg.
