The London 2012 Olympic Stadium could host rugby matches when the World Cup is held in England in 2015.
While the tenants of the Stratford location are yet to be determined, with West Ham United and Leyton Orient both in the running to relocate to the 80,000-seater stadium, rugby could become another of the countless sports to be staged at the venue.
The possibility of World Cup games being taking place at Stratford is dependent on whether a tenant is confirmed before the World Cup's organising committee submits between 10-12 potential venues to host the quadrennial tournament.
Although the likelihood is that Stratford will be an addition to the growing list of modern football stadia, rugby is played at several grounds in the Premier and Football League.
The Super League Grand final is annually played at Old Trafford and Manchester United's ground has also showcased England rugby union Tests. Hull City's KC Stadium, Reading's Madejski Stadium and Watford's Vicarage Road also accommodate rugby league and union fixtures.
Ross Young, chief operating officer of England's organising committee, said: "We have engaged with them from the very early part of this year and through the Olympic legacy company – you would be mad not to include it as part of your thinking.
Ticket sales are at the forefront of organisers' minds too. Cardiff's Millennium Stadium held four matches during the 2007 rugby World Cup despite France winning the right to host the tournament, and the 74,500-seater arena will also be used in 2015.
"To get as near as we can to the three million ticket sales, we have to engage with football clubs because they are the only ones who are going to give us the capacity to drive those numbers," Young said.
