The British and Irish Lions will proceed with their summer tour to South Africa after all alternative contingency plans were ruled out.
However, a number of obstacles still need to be overcome, with Lions board member Bill Sweeney confirming cancellation would be the only option left if it is unable to go ahead for any reason.
A joint statement outlined the decision to stage the event in South Africa, although it is understood that a reduced number of games and destination cities compared to the original eight-match itinerary is likely.
To underline Leonard's point, England's cricket team abandoned their tour of South Africa in December following a number of positive tests for coronavirus despite operating in a bubble environment.
"We have seen already in cricket when they went to South Africa and players halfway in said they did not feel comfortable with the protocols in place and the welfare issues in place. The side returned home," Sweeney said.
"We have to work with South Africa and make sure they have got the right environments there.
"We have to make sure the players' health and welfare is absolutely of a level we can accept."
