Dan Biggar, Taulupe Faletau and Leigh Halfpenny have been declared fit for Wales’ Six Nations clash with Ireland in Dublin.

The trio missed the 12-6 defeat to England at Twickenham on February 10, but have all returned to training.

George North, a second-half replacement at Twickenham, and Liam Williams are also fit to travel to Dublin.

“Everybody has been given the green light and we’ve got a few boys who are happy they scored at the weekend,” Wales forwards coach Robin McBryde told WRU TV.

“There were a couple of wins and some good performances so it’s great to have everybody back with a spring in their step.

“It’s nice to have a few selection headaches and plenty of players to choose from.

“There’s a competitive edge to training and there will be a few tough calls I’m sure, but we’re looking forward to those discussions.”

Fullback Halfpenny, who scored two tries in Wales’ opening Six Nations win against Scotland, missed the Twickenham defeat after picking up a foot injury.

Five-eighth Biggar suffered a shoulder injury playing for the Ospreys in the Champions Cup last month and No.8 Faletau has battled back after damaging knee ligaments.

North and Williams proved their fitness in tryscoring shows for Northampton Saints and Saracens respectively on the weekend.

Winger Josh Adams, who has started the opening two games, also crossed for Worcester.

“The fact we’ve been there before and had success is something we can draw on,” McBryde said.

“But every Six Nations is different, with different players and different circumstances. It’s a must-win game for us.

“We just need to find some of the finer details to make sure that ball is being delivered on a plate for our backs.”

Ireland currently top the table on points difference from England after winning their opening two games against France and Italy.
