Organisers of the tournament have unveiled the "Sully ball", designed by ball supplier Steeden in collaboration with Sullivan's family.

Sullivan made his international debut for Britain in 1967 and captained the side which won the World Cup five years later.

The Welshman, who died in 1985 at the age of 42, is considered a pioneer of the sport.

He scored 13 tries in 17 internationals for Britain, including a 60-metre try in the final of the 1972 World Cup against Australia.

Rugby League World Cup organisers said the match ball will "represent the core values of the tournament, the history of International Rugby League and recognise the significant positive impact Sullivan had on the sport".

"My father would be both honoured and humbled to see his achievements recognised in this manner," Sullivan's son Anthony Sullivan said. 

"He would, I am sure, take this opportunity to pay tribute to his teammates and the staff involved in that inspirational World Cup victory.

"For all of the family it will be very special to see him appreciated in this way and for his name to positively impact future generations within the sport."

The Rugby League World Cup had been scheduled to take place from October 23 to November 27 this year before being postponed after reigning men's and women's champions Australia, as well as New Zealand, pulled out due to COVID-19 restrictions.

It has been rescheduled for October 15 to November 19 2022.
