Chris White will set the Heineken Cup quarter-finals in motion - and move to within one match of a half century of tournament fixtures - when he takes charge of the clash between Cardiff Blues and Toulouse at the Millennium Stadium on Saturday, 11 April.
And while the leading English referee controls his 49th Heineken Cup fixture, Irish official Alan Lewis will be taking his tally to 59 matches later that afternoon when he is in the middle at the Walkers Stadium for the all-England contest between former Heineken Cup champions Leicester Tigers and Bath Rugby.
On Sunday, 12 April, Wayne Barnes (England) will be at Thomond Park when defending champions Munster clash with the Ospreys and Welshman Nigel Owens will bring the quarter-final weekend to a close at the Twickenham Stoop when Harlequins take on Leinster.
