The toss has taken place and Scotland will kick off. The players are in the tunnel and ready to come out to sing the national anthems. No rain as yet but it looks imminent.
The weather is fair at the moment but there has been rain in the air so conditions will be damp. There is a forecast for some heavy rain and wind during the match.
We have seen two massive pool games at the World Cup thus far with France beating Argentina and New Zealand getting over South South Africa. Will Ireland win here or will we see our first upset?
