'We are reliably informed that what Jonny needed was three to four weeks' rest,' said Lions manager Donal Lenihan. 'It is a concern when you see a fellow coming off the field two or three weeks in a row. He will be subjected to a medical along with everyone else before we leave on June 1.' Dallaglio has discussed his knee with Lenihan and said: 'If I have to have an operation, then I would think my chances of making the tour would be remote. I will have a clearer picture after the second scan and be able to make a decision by Saturday.'
