English Premiership leaders Saracens have already reported sales of more than 20,000 for the clash with the current top team in the RaboDirect PRO12 with three weeks still to go to the game on Saturday, 6 April.
The game sees Saracens director of rugby Mark McCall face his old side, while Ulster will be returning to Twickenham hoping to make amends for their 42-14 defeat there in last season's Heineken Cup final against Leinster.
Saracens have two massive London derbies to play before they meet Ulster, with reigning English champions, and fellow Heineken Cup quarter-finalists, Harlequins heading to Allianz Park on Saturday for one of the games of the weekend in Europe.
They then go to Adams Park, home of Amlin Challenge Cup quarter-finalists London Wasps, on Saturday, 30 March, for their final dress-rehearsal for their European showdown. Ulster will warm-up for their trip to English rugby's HQ with a re-run of the en of their Heineken Cup campaign last season, with away games against Edinburgh and Leinster.
Saracens saw Namibian World Cup star Jacques Burger make his long awaited return last week when he turned out for Bedford Blues against the British Army in the 'Mobbs Memorial' match. It was Burger's first appearance after a 14 month injury lay-off following knee surgery.
"It was great to be back playing against after so long out. I was nervous to tell truth as my first game back was such a big thing for me after spending all that time on the side lines," said Burger.
"It was a big step up from training to a competitive game, and in terms of my performance I didn't play incredible that's for sure. But I'm realistic and I know that I've got a long way to go to get back to where I was before, but part of me feels very proud to have got out there and to have played."
"As a club we've got a lot to look forward to, with some big games coming up in the Premiership and Heineken Cup. The guys who have played this year have been fantastic and are really on form at the moment and it'll be tough to get back into consideration that for sure."
