The inaugural IRB Junior World Championship is taking place in Wales next month. The tournament begins on June 6 when Ireland take on Argentina at Cardiff Arms Park, and with pool games to follow against New Zealand and Tonga, Elwood's charges will have to be at their best to finish as one of Pool A's top two sides.
After the game against Scotland, Elwood's squad will have one other warm-up fixture at Ashbourne RFC on Thursday week (May 29).
It will be a conditioned match against an Under-23 selection drawn from the Ireland 'A' Churchill Cup squad. Kick-off for that game is 4pm.
