Tigers gained qualification by topping Pool 3 and were paired with Guinness Premiership rivals Bath in the last eight of the competition.
“Demand for tickets for such a major fixture between two historic rivals is sure to outstrip the capacity of Welford Road,” said Leicester Tigers managing director David Clayton.
“Redevelopment work at our home stadium also requires the demolition of the current Caterpillar Stand during April, which would mean reduced capacity at Welford Road.
“Also, we must reserve 25 per cent of available tickets for the away club and, taking all of these factors into consideration, we believe that hosting the quarter-final at the Walkers Stadium is the best option available to us.
“Moving the game allows us to attract an even bigger crowd and we hope the supporters can play their part again.”
Leicester Tigers chairman Peter Tom CBE added: “The great thing about Leicester is that the clubs – the Tigers, City and the County Cricket Club – have a great relationship. Milan Mandaric has been very good in allowing us to use the Walkers Stadium.”
Tigers have already agreed to move the final home game of the Guinness Premiership season, against Bristol on Saturday, April 25, to the Walkers Stadium as work on the new Caterpillar Stand continues in readiness for its opening for the start of the 2009/10 season.
Leicester City chief executive Lee Hoos said: “We have a magnificent stadium, which is ideally suited to staging such high-profile events. We have an excellent working relationship with the Tigers, which is beneficial to both clubs. We wish them all the best in their quest for European glory.”
