There are no changes to the starting line-up of the team that played London Wasps last Sunday. Peter Richards continues as captain.
"This Sunday's visit to Cardiff provides another opportunity for our players to show what they are capable of," said Toby Booth, London Irish Head Coach. "We were pleased with the way the team, especially our younger players, performed in our opening match in the competition last weekend. The game with Wasps proved that we have real strength-in-depth in our squad.
"On Sunday we face experienced and talented opponents on their home pitch and that will help ensure that our squad remains match fit and battle hardened for the challenges ahead," Booth added.
