Organisers of Rugby World Cup 2015 are hoping to capitalize on the success of London 2012 and stage matches at the Olympic Stadium.
The tournament, which is the next world sporting event to be staged in England, starts exactly three years today.
England 2015 chief operating officer Ross Young said: "We would be mad not to include it as part of our thinking. Unfortunately there's still a bit of uncertainty about what exactly's going to happen with regard to full-time landlords for Olympic Park, but we have engaged with the London Legacy Development Corporation from the very early part of this year."
The organising committee are also detemined to take the big matches at the World Cup all over the country, which include plans for an England match being staged in the North.
England 2015 chairman Andy Cosslet added: "There is a tremendous appetite for making sure this World Cup gets to as many corners of the country as we can take it.
"Taking it out of the traditional rugby strongholds, where we are fighting the battle against Premier League football teams, is a priority.
"The RFU are very supportive of that. We haven't come to a final conclusion yet, but I think you will find there are a fair few northerners at the RFU like England head coach Stuart Lancaster and chief executive Ian Ritchie, so I am sure that we can do the right thing."
