Two South African sides and one from Australia are expected to get the chop when Sanzaar tonight finally drops the axe on three teams for next year's Super Rugby season.
South African newspaper Rapport reported that South Africa's Southern Kings and Cheetahs and the Western Force from Australia are set to be culled in a move that would see the struggling competition return to 15 teams, from 18.
Sanzaar last night said chief executive Andy Marinos would tonight (8pm NZT) announce details on the future of the competition and the tournament format, at the conclusion of round seven matches.
According to Rapport the new format will consist of three groups of five teams, with the Jaguares from Argentina playing in a round robin stage with the four remaining South African teams - the Lions, Bulls, Stormers and Sharks - from 2018's edition.
The Japanese Sunwolves are set to join the four Australian teams - the Waratahs, Brumbies, Reds and Rebels.
