O'Driscoll reveals Twickenham illness

Ireland skipper Brian O’Driscoll has revealed he was troubled by a virus during Saturday’s 20-16 RBS 6 Nations victory over England at Twickenham.

O’Driscoll missed the eve-of-match captain’s run after being struck by the illness and was still not operating at full throttle by the time the match started 24 hours later.
