Ulster will play Saracens at the home of English rugby, Twickenham.
The Premiership club - coached by former Ulster coach Mark McCall - confirmed on Wednesday they would stage the Heineken Cup quarter-final tie at Twickenham on Saturday, April 6 (kick-off 6.30pm)
Saracens new Allianz Park home, complete with its artificial playing surface, had been mooted as a possible venue.
But club chairman Nigel Wray said: “We look forward to playing this important match at the home of English rugby, a ground that many of our players know extremely well,” Wray said.
“It is absolutely clear that people want to see big teams playing big matches at big stadiums, and that is precisely what we will deliver at Twickenham.
“We did consider the option of playing this showpiece match at Allianz Park, our brand new home stadium in NW4, but, in consultation with local residents and our partners at the London Borough of Barnet, we have decided to settle at the new venue before applying to stage a one-off event with a larger capacity.”
Ulster’s last appearance at Twickenham was in the Heineken Cup final last May when they lost to Leinster.
