Riordan gets nod for Connacht
The Galway native, who graduated from the ranks of Colaiste Iognaid and Corinthians, makes his first start of the season at full-back.
Riordan, who made seven appearances in his first campaign last season off the bench, was in superb scoring form in pre-season, notching five tries in the games against Narbonne and Rotherham. His call-up is one of three changes, with John Hearty coming in for the injured Paul Warwick, while Matt Mostyn moves from full-back to the right-wing to the exclusion of Conor McPhillips.
