After the withdrawal of champions Australia and New Zealand, the Rugby League World Cup held in England this year was postponed until 2022.
The two countries withdrew from the game on the grounds of "player welfare and safety issues" related to Covid-19.
The World Cup was originally scheduled to be held in Newcastle on October 23 and included men's, women's, and wheelchair events.
"Let us continue to play becomes infeasible and irresponsible," said Jon Dutton, the chief executive of the tournament.
"I think it will take some time for the International Rugby League to recover from this situation. I hope we can be a beacon.
"Of course, we give priority to the voice of the players and the choice of players. We know that players want to participate in the game. We take our responsibilities very seriously. We are determined to host the largest and best Rugby League World Cup ever.
"This year cannot be a real regret, but leadership is to make difficult decisions and be responsible. We do this not only for the best interests of the championship, but also for the best interests of the rugby league sport."
Australia's take over the World Cup, winning eight of the past nine World Cups dating back to the 1970s. New Zealand’s top players also participated in the NRL and won the 2008 World Cup hosted by Australia.
