Andrew Porter returns at loose-head prop to shore up Leinster’s front row in Saturday’s semi-final against Toulon at the Aviva Stadium.
Porter hasn’t played since picking up an injury in the last-16 win over Edinburgh at the start of April.
However, fellow Ireland international Tadhg Furlong is missing after limping out of the defeat by Benetton at the weekend, with Tom Clarkson coming in at tight-head.
Joe McCarthy and James Ryan are paired in the second row, while Harry Byrne steers the side from fly-half and All Black Rieko Ioane is on the wing.
Toulon include former England prop Kyle Sinckler and Scotland scrum-half Ben White in their starting line-up, with Junior Kpoku, who won the under-20 World Cup with England’s age-grade side in 2024, earning the nod at blindside flanker.
South African-born second row David Ribbans, who won 11 England caps between 2022 and 2023, captains the side.
