The squad will depart for South Africa on Sunday, June 5 and will be based in Cape Town ahead of the first Test at Newlands (June 11) before moving to Johannesburg for the second Test at Ellis Park (June 18).

The third and final Test will take place in Port Elizabeth at the Nelson Mandela Bay Stadium (June 25).

Roux is one of two uncapped players who have been included in head coach Joe Schmidt’s squad, with New Zealander Sean Reidy also cracking the nod.

Roux played lock for Western Province in 2011 and 2012, before signing for Leinster. He was loaned out to Connacht in 2014 and signed a permanent deal with the club last year.

“Touring South Africa will be arduous to say the least so we’ve attempted to prioritise players who are currently as close to full fitness as possible. In what is always a difficult balancing act, we’ve taken a long term view with a number of players who need a rest or will benefit from a full pre-season,” Schmidt told the IRFU’s official website .

Players unavailable for selection include Cian Healy, Denis Buckley, Nathan White, Josh van der Flier, Peter O’Mahony, Sean O’Brien, Tommy Bowe, Andrew Conway and Simon Zebo.
