Ireland head coach Noel McNamara has been forced to make two changes for tomorrow's World Rugby under-20 Championship match against Australia.
Rob Russell comes in at full-back for Iwan Hughes, who has suffered a finger injury.
With flanker Azur Allison continuing the return-to-play protocols, there is a start at openside for Ronan Watters, while Sean French has been ruled out of the rest of the tournament with a facial injury.
Angus Kernohan and Jonathan Wren are named on the wings, while the rest of the back line is unchanged with Craig Casey and Jake Flannery in the halfbacks and Stewart Moore and Liam Turner in the centre.
The front five remains the same also with Josh Wycherley, Dylan Tierney-Martin and Thomas Clarkson in the front row while captain Charlie Ryan and Ryan Baird pack down in the second row.
Josh Hodnett moves from 7 to 8 in place of Allison, in between Watters at open-side and David McCann at 6.
Aaron O’Sullivan and Max O’Reilly have been called up to the squad in place of French and Hughes but will not be in the side this weekend.
