Grand Slam winners Fiona Coghlan and Nora Stapelton have returned the Women's RBS 6 Nations trophy to Chief Executive John Feehan at the Six Nations offices in Dublin.
Hurley - a member of the Munster Academy - comes into the backline with both Mark Kettyle and Ross McCarron sidelined through injury.
Ireland have made two changes and one positional switch from the side which lost 20-13 to France last time out at Thomond Park.
With London Irish's Kieran Geraghty benched, Daniel Riordan will look to impress on the left wing, with regular Paul McKenzie - the sole try-scorer against the French - moving onto the right flank.
The pack - led by a trio of Dungannon's youth talent - is unchanged.
Hurley was earlier this week named in the Munster Development squad for their match with the local Euskarians side in San Sebastian - on the same weekend - April 2/3 - as Munster's Heineken Cup quarter-final tie with Biarritz.
It could prove a baptism of fire for Hurley and Riordan however, with a win for Wales notching up their third Grand Slam at U-21 level since 1999.
The travelling Ireland squad contains just four - including captain Gareth Steenson - of the side which finished runners-up at last summer's U-21 World Cup in Scotland.
