Porter and Farrell will make Six Nations debuts for Ireland against Wales

"If you look at Ports firstly, over the a year ago and a half what he's had to take in his stride - changing sides of the scrum, how he's developed that part of his game - it's more exciting than nervous to see what he's going to provide", said Healy.

15-Rob Kearney, 14-Keith Earls, 13-Chris Farrell, 12-Bundee Aki, 11-Jacob Stockdale, 10-Johnny Sexton, 9-Conor Murray; 8-CJ Stander, 7-Dan Leavy, 6-Peter O'Mahony, 5-Devin Toner, 4-James Ryan, 3-Andrew Porter, 2-Rory Best (captain), 1-Cian Healy.

Chris Farrell is expected to come in for Robbie Henshaw at outside centre after the Leinster man's injury against the Azzurri, while CJ Stander resumes Test duties at the base of the scrum, with Jack Conan among the replacements.

Replacements: 16 Sean Cronin, 17 Jack McGrath, 18 John Ryan, 19 Quinn Roux, 20 Jack Conan, 21 Kieran Marmion, 22 Joey Carbery, 23 Fergus McFadden. "That's the biggest carrot for us", Biggar said. "You don't suddenly replace world-class players".

Tindall thinks Scotland's expansive style could give the holders a chance to show what they are capable of with ball in hand after thrashing its rivals from north of the border 61-21 in the Calcutta Cup showdown a year ago.

"Eddie Jones has talked about hunting and going after teams and at the moment I don't think he's really got them to do that, but this Scotland defense could provide that opportunity".

Ireland host Wales, having so far defeated Italy and France.

Dan Biggar returns from injury and starts at fly-half, with Liam Williams and Leigh Halfpenny also back after missing the England match.

"Last year we let our emotions get to us a little bit too much", the 30-year-old told reporters.

Ireland have usurped defending champions England as the team most likely to win the Six Nations ahead of this weekend's third round of fixtures, according to mathematical modelling.

England won their opening two matches of this year's competition, against Italy and Wales.
