Six Nations: Farrell starts for Ireland at Scotland

Six Nations: Farrell starts for Ireland at Scotland

But Schmidt has moved to defend his approach ahead of their trip to Murrayfield to face Scotland on Saturday. So when you lose you get at least three letters.

"I think it will be a very fast, very physical game, a fantastic game to watch". And we try to vary our defensive game.

In the backline, centre Chris Farrell will make his first Six Nations start, while fullback Rob Kearney replaces Robbie Henshaw, who has fallen out of the match 23.

The only other change sees Sean O'Brien favoured over Leinster teammate Josh van der Flier at flanker.

Scotland are unbeaten in seven home Six Nations matches since losing to England in February 2016 and the progression of Edinburgh and Glasgow to this season's European Champions Cup quarter-finals has given them an extra boost.

That injured trio have now been joined by Robbie Henshaw, who according to Schmidt has failed to shake off a dead leg. "It's just a bit of aggravation after having a knock".

"It does make it hard". It does make it hard; the problem is he maybe could have played. "But if you get another bump on it, it debilitates you quickly, and then you have to make another change". "It probably took us until today to really get a spring back in our step and really get hungry because we can't pass up a second opportunity".

"He just got a dead leg and it hasn't recovered sufficiently so we're just gonna have to forge ahead".

Roux, who came off the bench against England last week to earn his ninth Test cap, replaces the injured Devin Toner.
