Wallabies' playing stocks take another hit with Matt Toomua forced home through injury Toomua will take no further part in the Wallabies' spring tour. AS if the Wallabies' preparations for the Scotland Test this weekend could not get any more shambolic, it has emerged that star centre Matt Toomua is flying back to Australia after suffering a hamstring injury. It means the Wallabies will potentially field a revamped backline featuring four starting players who did not start last week against Ireland. The centre partnership of Toomua and Tevita Kuridrani is gone, with Kuridrani handed a five-week suspension from the IRB for a tip-tackle on Ireland's Peter O'Mahony last weekend. Starting wingers from that match, Adam Ashley-Cooper and Nick Cummins, have both been suspended for going out drinking until the early hours of last Wednesday, four days before the Test match. The mass losses leave coach Ewen McKenzie scraping the barrel for replacements. All Blacks great Andrew Mehrtens says Wallabies fans need to be patient while coach Ewen McKenzie shapes the teams' culture. He has already been forced to call in winger Peter Betham from Sydney, and might have to add him to the reserves' bench despite the player flying 24 hours across the globe three days before the game at Murrayfield. The forward pack is likely to remain unchanged, but the only expected survivors from the backline at Lansdowne Road appear to be Will Genia, Quade Cooper and Israel Folau. Toomua trained throughout Tuesday's session, but afterward a scan revealed he had a low grade tear to his hamstring. "Matt has had a fantastic season and has done a terrific job for the Qantas Wallabies in a new position," McKenzie said. It's extremely disappointing to lose him at this point and not have him available for our final two games. However, he's shown all the positive attributes we want in our players and are looking forward to seeing him use his international experience to continue his development during the Super Rugby competition next year. The Australian Rugby Union will wait to receive a written judgement today before considering its options on whether to appeal Kurudrani's ban. Kuridrani was charged under Law 10.4 (j) which states "Lifting a player from the ground and dropping or driving that player into the ground whilst that player's feet are still off the ground such that the player's head and/or upper body come into contact with the ground is dangerous play."
