Six Nations Week 3 team news: Costelow back at fly-half for Wales،

After a weekend off following the opening two matches, the Six Nations returns on Saturday with Ireland looking all-conquering, England undefeated and Wales still searching for their first win of the tournament.

England travel to Murrayfield to face Scotland on Saturday after Ireland host Wales, ahead of Sunday's clash between France and Italy.

Here's all the team news and everything you need to know ahead of the weekend.

Ireland vs Wales, Saturday 2.15pm, Aviva Stadium, Dublin

Sam Costelow returns to fly-half for Wales after suffering an injury during their clash with Ireland in Dublin on Saturday, the only change to the team since their last Six Nations outing.

Costelow missed the 16-14 defeat to England in their previous match two weeks ago with a neural neck injury, but is back in the squad that manager Warren Gatland named on Tuesday.

Cardiff number 8 Mackenzie Martin has been named among the substitutes for the first time and is in line for his first cap if he faces the Irish.

The 20-year-old from Cardiff replaces Taine Basham in the 23-man squad and could become the 1,200th Welsh international.

Costelow, 23, was sent off in the first half of Wales' opening match against Scotland and his replacement Ioan Lloyd, also from the Scarlets, helped orchestrate a fightback as they came back from 27-0 to one point away from obtaining a result.

But Lloyd returned to the bench after an ineffective performance against England at Twickenham.

Wales are seeking their first success in this year's Six Nations, but face a rampant Ireland, who have won both of their opening matches.

We're excited to be going to Dublin and competing against one of the best teams in world rugby. It's a challenge we're relishing,” Gatland said in a statement.

“We've made progress over the last two games and now it's about building on that, learning from those experiences and taking that into account this weekend.

“It’s about continuing to work hard, looking for precision in our performance throughout 80 minutes and also keeping our discipline,” added the coach.
