“It would meet the Lions’ requirements from a performance point of view,” a source said. “There have been conversations around Vegas, Chicago and LA.
“We have talked about one game potentially outside of New Zealand. The tour will be different, but we’re not sure how much yet. We think there’s an opportunity to do something in another market on the way down to New Zealand. But it is five years away.”
Telegraph Sport understands, too, that although the location and destinations of Lions tours are constantly under assessment, there are no plans to take a full tour away from the three traditional host countries: Australia, New Zealand and South Africa.
New Zealand are the trailblazers in hosting matches in the US. Their first loss to Ireland, in 2016, took place at Chicago’s Soldier Field and this year the All Blacks defeated Fiji in San Diego. Next year, an Irish rematch is also expected in Chicago.
Should Las Vegas be selected as a destination for a fixture, Sin City will already have had experience of hosting oval-ball matches. In March, the NRL began its inaugural Rugby League Las Vegas event, which had two fixtures take place at the Allegiant Stadium in Nevada on the opening round of the season.
That initiative is contracted until 2028, with Super League mirroring the concept and hosting Wigan Warriors and Warrington Wolves there in March.
The Lions participating in matches away from its traditional triumvirate is by no means a new concept. A Combined British side took on Argentina in a one-off test in 1910, with a full tour of that country following in 1927, under the Lions name.
Other destinations for Lions matches include Nairobi and Paris and, while the US has no experience of the Lions behemoth, neighbouring Canada hosted a test in Toronto in 1966.
Telegraph Sport approached the Lions for comment.
