NOEL MCNAMARA HAS made just two enforced changes changes to his Ireland U20 side as they bid to build on Tuesday’s victory over England in tomorrow’s World Rugby U20 Championship meeting with Australia in Santa Fe (kick-off 14.30 Irish time, eir Sport).

However, the win over England came at a cost for Sean French and starting fullback Iwan Hughes.

French, who played a starring role during the U20 Grand Slam success, suffered a facial injury during his impressive cameo off the bench on day one. Hughes sustained a finger injury and both men will miss the remaining four games of the tournament.

Leinster pair Max O’Reilly and Aaron O’Sullivan will join the squad as replacements in time for the pool closer against Italy.

Injury to French and Hughes make further additions to a long list of absentees for Ireland U20, after Harry Byrne, Scott Penny, David Hawkshaw and Martin Moloney were all unable to travel to Argentina.

Despite the four-day turnaround between fixtures, McNamara has retained 13 starters to face the Junior Wallabies.

Rob Russell comes in at fullback to replace Hughes. And with back row Azur Allison continuing through return to play protocols after his withdrawal with suspected concussion, Ronan Watters starts at openside.

The reshuffle means John Hodnett reverts to number eight and, double try-scorer last time out, David McCann completes the back row.
