Warren Gatland's Lions are due to visit South Africa next July and August for a tour that will feature three Tests against the world champions.

However, the outbreak of COVID-19 could have a knock-on effect on that tour, with Northern Hemisphere countries facing up to the possibility of missing out on revenue from internationals that may have to be scrapped later this year.

A report over the weekend claimed the Lions' 2021 tour to South Africa could be cancelled entirely as World Rugby contemplates how to reschedule the calendar when the sport returns.

SA Rugby has insisted the Lions tour remains on, though it conceded the dates are being looked at.

"While we continue to look forward to an incredible tour by The British and Irish Lions next year, and there are no planned changes, it would be remiss of us not to explore various scenarios for a possible date change caused by the COVID-19 pandemic,” said an SA Rugby spokesperson.

The Lions last toured South Africa in 2009, losing 2-1 to the Springboks.

They have since beaten Australia 2-1 and drawn with New Zealand under Gatland.
