2019 USA Sevens
Among the reported reasons included the uncertain status of Sam Boyd Stadium with the upcoming stadium not due to be ready until summer 2020 , poor living environment at the team hotels ( the stadium is far distant from the main tourist area of the Las Vegas Strip ) , and safety concerns due to an unusually narrow pitch with team benches very close to the touchlines ( Sam Boyd Stadium is built for American football , a sport with a playing field about 20 metres narrower than a standard rugby pitch ) .
