Six Nations chief executive Ben Morel has ruled out the possibility of South Africa joining the northern hemisphere competition in near future.
Following the pandemic coronavirus, there were talks about a possible inclusion of the World Champions in the expanded version of the competition with South Africa Rugby chief executive Jurie Roux also expressing interest.
Nevertheless, Morel highlighted that Springboks are committed to the Rugby Championship competition until 2030 and currently they are 'cautious' about any expansion to the Six Nations tournament.
“It’s not currently a question. My understanding is that South Africa are committed to the Rugby Championship and at the same time our focus is on July and November,” Morel said.
“The Six Nations has added to and reduced its number of teams in very few moments during its 140 years, so it’s something that we’d be very cautious of doing.
"We're pretty happy with what we have, but we're sure it could be improved. If that leads to a final or some sort of ranking, that would be a positive.
"It's complex but the Six Nations are playing a leading role in what the solution could be. Some sort of final is exciting and that's what the fans want to see."
