When asked if he was confident it would go ahead, Gatland said: “Absolutely, yeah. I’m hearing positive things from both sides.
“I’m confident that with the discussions taking place, that it will get resolved today. There have been half-a-dozen meetings over the last few days or so.”
Gatland has postponed Wales’ team announcement – which was due at lunchtime on Tuesday – until Thursday because of the stand-off.
When asked if he had been given assurances the round three match at the Principality Stadium would take place, Gatland replied: “Not at the moment.”
