Umaga refuses to comment on O'Driscoll clash

New Zealand captain Tana Umaga has refused to explain his part in the incident which resulted in Lions captain Brian O’Driscoll being ruled out of the tour with a dislocated shoulder.

Less than two minutes into the first Test in Christchurch, O’Driscoll was the victim of what the Lions camp described as a double spear tackle which left him flat out on the ground holding his damaged shoulder.
