Noel McNamara's side are unbeaten so far in this season's British & Irish Cup, collecting maximum points from the back-to-back games against Bristol in December and in the opening two rounds back in October. They top Pool 2 by five points, ahead of Doncaster Knights who visit Donnybrook next week.

Cathal Marsh will captain Leinster 'A' in a half-back pairing with Charlie Rock who comes in to start against Cardiff having appeared from the bench in the last round against Bristol. The only other back-line change from that game sees Jack Kelly named on the right wing in place of Hugo Keenan who is in South America with the Ireland Sevens squad.

There is an all-new front row for Saturday's round 5 game in Wales with Peter Dooley, Ronan Kelleher and Jack Aungier all selected to start. Mick Kearney comes in to partner Ian Nagle in the second row.

Max Kearney, who captained Belvedere College to their second successive Leinster Schools Senior Cup title last March, is named in the back row with the senior-capped Josh Murphy and Peadar Timmins.

Speaking to leinsterrugby.ie ahead of this weekend's match, Leinster 'A' head coach McNamara said: "We've put ourselves in a strong position - the four wins from four has been great. It's important now in these next two games that we get results to give us the best possible opportunity to advance in the competition.

"We feel we've done well up to this point but it's important for us to hammer that home over the course of the next two weeks. The great thing about Leinster 'A' is it's a Leinster selection - there are guys from the sub-Academy right the way up to senior players.

"It's an opportunity this week for a couple of younger guys. Max Kearney is making his debut, but also Jack Aungier and Ronan Kelleher are making their first starts. The Cardiff team is experienced, they've got Welsh internationals involved, so it's going to be a big test."

Leinster 'A' return to Donnybrook on Saturday week (January 20) to play Doncaster in a game that could determine who tops the pool and progresses to the quarter-finals with home advantage.
