Garry Ringrose will not get the opportunity to play in a Test for the British and Irish Lions in Australia as he undergoes return to play protocols. However Mack Hansen is poised to make his Lions Test debut against the country of his birth, while Joe McCarthy is in the frame to return to the second row after missing the dramatic second Test that clinched the series win for Andy Farrell's squad. Ringrose, 30, was due to start last Saturday's game at the MCG but self-reported concussive symptoms 48 hours before the game and Huw Jones replaced him at outside centre. Lions attack coach Andrew Goodman has now confirmed that the Dubliner is going through a 12-day return to play programme because he had previously suffered concussion after the Lions' victory over the Brumbies and so will miss out on Saturday's final Test in Sydney. "He’s disappointed, as you can imagine," said Goodman. "Garry was playing some amazing rugby through this tour. It’s been a dream of his for so long to represent the Lions and he’s managed to do that. But he wanted to be a Test-match Lion so it’s been devastating for him. "To his credit, he’s been good around the group. Anyone that knows Garry, he’s a great lad and a team man so the boys have all been disappointed for him. "Obviously he’s disappointed for himself but he’s getting around everyone and making sure he helps prepare everyone as much as he can. He’s a real leader for us in terms our backline in particular, so he’s been great." Hansen missed out on selection for the first two Tests due to a foot injury but, along with McCarthy, played a full part in training today as the Lions returned to work following an extra day off to celebrate the series win. "I think everyone was impressed with Mack's efforts off the ball through the opportunities he's had - work rate, kick-chase, scramble defence, he works really well off his wing to make an extra number on the long edges," said Goodman. "He communicates very well and I think all of the inside backs appreciate his composure off the ball and the chat he gives. It's been a big strength of his, his work off the ball but also his composure and the way he sees the game. He grew up playing a lot of 10 so he's really smart around what he sees and making the right calls off the back of that. "For this time of the tour, it’s amazing how many people we’ve got available. Unfortunately, Garry has been ruled out of this Test match, but we have Mack, Joe, Sione (Tuipulotu) all out there running today, so they’re in contention." Farrell and his coaching staff must decide how far to go in terms of freshening up the matchday 23 and giving other players - including the 2022 World Player of the Year, Josh van der Flier - a taste of Test action. "There's some great competition, guys who haven't played Test matches and would die for the opportunity to do so," acknowledged Goodman. "Again, we've got to do what's best for the squad and the 23. Cohesion versus freshness. It's going to be a long process as it always will when we sit down after dinner to have a good chat after that. "Did you see Tadhg Furlong?... Everyone's seen that interview he gave. Someone like him has been on three tours and he doesn't want it to end. That's a prime example. It's probably going to be his last opportunity to wear a Lions jersey and it's been a massive part of his career. "There are a number of guys in that boat who just want to keep going because it's a special time and they want to be part of history, finishing the tour off well. Whether it's your first tour or third tour, everyone wants to keep competing." Get the latest sports headlines straight to your inbox by signing up for free email.
