Pat hopes to feature in Saturday's match and told the Evening Times: "For me it is going to take 80 minutes of controlled mayhem to beat Leinster at the RDS on Sunday. We know that we are going to have to battle as if our lives depend on it at every breakdown and in every piece of contact it is going to have to be full metal jacket from start to finish.
"Up front we are going to have a real go at the Leinster scrum. We know that it is one of their strong points and it is more than possible we could be facing an all-Ireland front row, but our scrum has been a massive weapon for us this season and we want to put it all on the line come Saturday night.
"We believe that there are weaknesses for us to exploit in their scrum and it is up to us as a unit to ask the questions that will help make it creak. This is going to take everything we have in the tank and we are ready to produce that."
