Ben Evans has had surgery after rupturing his hamstring against St Helens . Warrington 's Wales international Ben Evans is set to spend around four months recuperating from a ruptured hamstring . The 22-year-old prop suffered the horrific injury during the Wolves ' 32-24 defeat by Super League leaders St Helens last Thursday . He spent the weekend in London , where he underwent surgery , before returning to Warrington on Sunday night . 'It was a particularly nasty injury and he was in a considerable amount of discomfort at the time , ' Warrington assistant coach Richard Agar said . 'But they got him off to hospital as soon as they possibly could and got him down to London the next day to see the specialist . 'He 's had a fairly extensive operation to re-attach it but it 's going to be a long injury . The first estimates are around four months but all that will depend on the success of the operation and how he rehabs . 'If it goes well for him , he will have a chance of playing again this year and at this place he is going to get the best medical care . ' The Wales international ( centre ) will be sidelined , alongside brother Rhys , for around four months . Evans will have the company of his twin brother Rhys , the Warrington winger , during his recovery period . Rhys underwent shoulder surgery after damaging it during the Wolves ' World Club Series clash with St George Illawarra in February and is facing a similar length of time on the sidelines . 'It 's sad for Ben because he 's got an opportunity that he had been patiently waiting for , ' added Agar . 'Both him and Rhys have now picked up sizeable injuries and will be out for a similar length of time . '
