The next head coach of the British and Irish Lions, widely expected to be Warren Gatland, will again face the challenge of being without England's leading players at the start of the tour after Premiership Rugby confirmed that its final will take place on May 27, seven days before the Lions' first match in New Zealand.
It underscores the need for a shake-up of the global season, which is being discussed by World Rugby.
The Lions play their first match, against a New Zealand Rugby Provincial Union XV, on June 3 in Whangarei. They face the Auckland Blues four days later and the Canterbury Crusaders on June 10.
Players involved in the English final are almost certain to miss the opening game and will travel to New Zealand without any time with the squad, who are likely to assemble two weeks before they depart for the tour.
Players in the French Top 14, such as Toulon's Leigh Halfpenny, are also in danger of missing out completely as their competition runs into mid-June. The Lions have said they want to avoid players joining the tour late.
