Michael Cheika says he has no fears about throwing young forwards into the fray against a physical Argentina pack as he prepares to hand Lopeti Timani his run-on debut at Twickenham this Saturday.Timani is competing with the Bath-based Leroy Houston for the Wallabies No.8 spot and replaces the injured Sean McMahon, who is expected to miss a month with syndesmosis picked up in last weekends loss to South Africa in Pretoria. Houston may yet earn a Test debut via the bench, which has yet to be finalised.The towering Rory Arnold is also likely to be drafted in at lock, where he will partner fellow young gun Adam Coleman, at the expense of Rob Simmons in the only other change to the starting line-up from the 18-10 defeat.Simmons passed all concussion protocols after suffering a head knock against the Springboks but is expected to be axed as Cheika searches for the best combination.In opting for the relative inexperience of Timani (one Test) and Arnold (four Tests), Cheika said the Wallabies could have no fear in backing young stars.We cant be frightened to do that. No matter what game it is, whether its Argentina (or anyone else), he said.Timani, who came off the bench in the victory over Argentina in Perth last month in his only Test to date, would bring some much-needed size and aggressive running at Twickenham on Saturday, Cheika said.With the versatile Dean Mumm - a lineout specialist - making his home at No.6, Cheika believes the Wallabies need a hard-runner at the back of the scrum in the mould of veteran Wycliff Palu.I think with the profile of the other players we have, like the sixes who are more the jumping-type sixes, that ball-carrying, Wycliff Palu-style No.8 is something that we want to have as well, Cheika said.We want to be able to do both. Leroy is quite an abrasive runner as well, so theres a great opportunity to (see) how hell go with the step up.Arnold has impressed off the bench, and Cheika hopes he takes this weekend is a chance to prove he deserves to be a long-term starter.Hes just been aggressive, his lineout jumping has really improved, his mobility and ball carrying... and every time hes come onto the field from the bench hes made an impact as a finisher, Cheika said.I just think its a real opportunity for him.Likely Australia XV:?15.
