The Lions have rejected Australia’s offer to host the summer series against South Africa.
The board meeting on Friday came to a decision due to a lack of financial certainty about the finances of Australian Rugby holding the eight-match round, which culminates in a three-match series against the Springboks.
Four options are being considered but each has major disadvantages with a decision due this month.
Going forward with the original itinerary in South Africa could be either with a small population or behind closed doors, while also exploring the financial potential for risk tour in Britain and Ireland.
Postponing it until next year is the most likely course of action due to the ramifications for home union summer tours, and postponing it is the last resort.
The South African board will meet next week with global competitors likely to host the Lions behind closed doors getting a move.
