Big boots.

Ireland boss Andy Farrell looks set to make at least one forced change to his team ahead of their return to Six Nations action against Wales at the Aviva Stadium in Dublin this weekend.

Fullback Hugo Keenan looks increasingly likely to miss out after picking up a knee injury in the win over Italy in Round 2.

Keenan has started 32 of Ireland’s last 36 games at fullback and is recognised as one of the very best in the world at fifteen, leaving a huge gap to fill in Ireland’s backline this weekend.

Farrell has opted not to select an out-and-out fullback in his squad as cover with the Ireland boss set to look to the versatility of Ciarán Frawley, who was recalled after being released for URC action with Leinster during the break.

Ireland’s depth at fifteen has been questioned in the past but such is Keenan’s durability, it seldom becomes an issue. Frawley now looks set to fill in for Keenan on this rare occasion, with the regular in line to return for Round 4.

Big boots to fill, no doubt.
