It's down to the wire now for the five contenders who have been shortlisted for the ultimate individual accolade in northern hemisphere rugby, ERC European Player of the Year 2013.
It will be White's 10th Heineken Cup knock-out game when he controls the opening quarter-final between Llanelli Scarlets and Munster at Stradey Park on Friday, 30 March.
White is the only man to have refereed three Heineken Cup finals and was the official in charge when Munster won the title at the Millennium Stadium last season.
He has already refereed the Scarlets once this season, when they won 41-34 in Toulouse before Christmas.
Joel Jutge will be at Adams Park for the clash between London Wasps and Leinster on Saturday, 31 March, while Alan Lewis will be at Welford Road a day later for the re-match of the 2001 final between Leicester Tigers and Stade Francais Paris.
It will be the fourth time Jutge has been in charge of a knock-out game involving Leinster. He was in the middle when Munster ran out 30-6 winners in last season's semi-final at Lansdowne Road, when Leicester Tigers won the 2005 quarter-final at the same venue 29-13 and at Welford Road in 2002 when the Tigers triumphed 29-18.
It will be his third game involving London Wasps, and he was in charge of the quarter-final at Adams Park in 2004 when the home side beat Gloucester 34-3 on their way to the title.
Lewis has already taken charge of five Heineken Cup quarter-finals and one of those was at Welford Road when the Tigers beat Swansea 41-10 in 2001 on their way to a final shoot-out with Stade Francais at Parc des Princes.
The Irish official has refereed both sides in the tournament this season - the Tigers at the Millennium Stadium when they beat Cardiff Blues 21-17 and Stade Francais at Parc des Princes when they overcame English champions Sale Sharks 27-16.
Nigel Owens, who was on duty in every round in the Pool stages, will go into his first Heineken Cup quarter-final hot on the heels of having controlled his first RBS Six Nations match this season between England and Italy at Twickenham.
