Garry Ringrose will captain the Leinster team to take on Racing 92 in the opening weekend of the Heineken Champions Cup tomorrow at 2pm.

The back-three remains the same as it was in last weekend’s URC win over Ulster Rugby. Hugo Keenan starts at fullback, with Jimmy O’Brien and James Lowe on the wings.

Ringrose is joined in the centre by Charlie Ngatai. The New Zealand international makes his European debut for the province.

Ross Byrne and Jamison Gibson-Park form the half-back partnership for the second weekend in a row.
