Lions 2013: former Wales wing Shane Williams handed surprise call-up for Brumbies game in Canberra Explaining the decision to turn to Williams, Gatland said: "We told him we needed him for one game - he was already halfway here and part of the reasoning behind that is that he is still playing and thinking about the travel of getting players here." Roberts will today discover the full extent of his injury after being forced to limp off during the second half against the Waratahs, but he looked to be in considerable pain when he left the field. George North (tight hamstring) and Manu Tuilagi (shoulder) are also facing a battle to be available for selection this week, while Tommy Bowe has already been ruled out of the first Test with a broken hand. The selection of Sean O'Brien, Justin Tipuric and Toby Faletau in the back row to face the Brumbies suggests that Lions captain Sam Warburton, Toby Croft and Jamie Heaslip all did enough against the Waratahs to book their places in the Test side. Roberts's injury cast a shadow over an otherwise very positive day for the Lions. It was their biggest win over the Waratahs NSW and fullback Leigh Halfpenny, with 30 points from two tries and eight successful kicks, broke a record for a Lion in Australia and was within seven points of the all-time individual points scoring record. Ulster and Ireland hooker Rory Best will captain the side against the Brumbies and Scottish full back Stuart Hogg makes his second appearance on tour as No 10 following his successful outing against the Combined Country XV. Rob Kearney gets his first start, while scrum half Ben Youngs is the only other player in the starting XV who had game time against the Waratahs. British and Irish Lions: R Kearney, C Wade, B Barritt, B Twelvetrees, S Williams, S Hogg, B Youngs; R Grant, R Best (capt), M Stevens, I Evans, R Gray, S O'Brien, J Tipuric, T Faletau. Replacements: R Hibbard, A Corbisiero, D Cole, G Parling, D Lydiate, C Murray, O Farrell, S Zebo
