A video clip has surfaced of a conversation between Tiger Woods and Rory McIlroy and the subject was not golf-related.

No, it was a Japan Skins conversation between the duo on the Rugby World Cup that winds-up this weekend with England tackling South Africa.

It was much like explaining to any American, the in’s and out’s of cricket but on this occasion it was Tiger asking the questions and Rory providing the answers … well trying to supply the answers as they walked the Accordia Narashino course in Chiba, Japan.

In a video released on the official Rugby World Cup Twitter page, McIlroy can be overheard explaining how long the 2019 Rugby World Cup was being held.

It was two days after McIlroy had been present to watch his Ireland side trounced by New Zealand and with McIlroy first explaining to Woods that the New Zealand All Blacks would play England in one semifinal and South Africa would tackle Wales in the second semifinal.

But it wasn’t the format or the teams involved that impressed Woods, he was more taken by how long the players spend away from home.

Tiger then follows up with a question, asking “how long are they there for?”

“With warm-up games and the comp, the whole thing is about three months, but they probably get here a week before the first game so…”

Tiger could be heard exclaiming: “A month and a half.”

“That’s a commitment,” Woods says.

“It might be eight weeks if you make the final,” McIlroy whispers as Jason Day lines up a putt from the other side of the green.

Woods then branches out on his rugby knowledge as he moves McIlroy’s attention to something closer to home.

Seemingly not even batting an eyelid that Woods knew what the Lions tour was, McIlroy goes on to explain the Lions only tour once every four years to South Africa, New Zealand and Australia.
