'Instrumental' Dan Sheehan would be 'big loss' for Ireland – Mike Catt

Assistant coach Mike Catt admits injured hooker Dan Sheehan is “instrumental” in Ireland’s style of play and would be a “big loss” for the Rugby World Cup.

Sheehan put a dampener on Saturday’s 29-10 victory over England by limping off shortly before half-time, with Ireland’s coaching staff still anxiously waiting to discover the extent of his foot issue.

The 24-year-old remained in Dublin for treatment as Andy Farrell’s men flew to France to prepare for this weekend’s final warm-up match, against Samoa in Bayonne.

Rob Herring, Ronan Kelleher, Tom Stewart and the uncapped Diarmuid Barron have travelled and will seek to stake their claims for the number two role.

Catt insists Ireland’s coaching team have full confidence in the back-up options but concedes potentially losing “world-class” Sheehan for part or all of the World Cup, which starts on September 8, would be a major blow.

“I think what you get from Dan, he’s one of the best hookers in the world currently, so he’s going to be missed in whatever team he plays in,” he said.

“But we’ve got full faith in Rob Herring and Ronan Kelleher and Tom Stewart.

One final hit out in Bayonne this weekend!
