Ireland under-20 coach Nigel Carolan has made 12 changes to his starting line-up for the World Rugby Under-20 Championships semi-final against Argentina in Manchester on Monday (5.30pm).

Influential skipper James Ryan returns to the secondrow after recovering from a thigh injury, one of seven changes to the pack from the win over Georgia, with blindside flanker Greg Jones the only player remaining in the forward unit. In the backs outhalf Johnny McPhillips and left wing Hugo Keenan are the two players that remain.

Speaking ahead of the semi-final at Manchester City Academy Stadium, Carolan said: “The players have done really well to get themselves into a World Championship semi-final.

“There’s a great belief amongst this group and they’ve shown what they can do as a team over the course of the last number of games.

“Argentina are going to present another big test for us. They have a lot of physicality up front as well as pace out wide so we are going to need to be at the top of our game tomorrow.”

The match will be broadcast live on TG4 and Sky Sports 3 and will be refereed by Craig Maxwell-Keys of the RFU.
