NEWPORT Gwent Dragons teenager Tyler Morgan will go up against Keith Earls on Saturday when the Lions tourist ends a 29-month Test absence.

The centre will start for Six Nations champions Ireland in the World Cup warm-up against Wales at the Millennium Stadium while lock and fellow Munsterman Donncha Ryan also returns to the international scene.

The pair will make their first Test appearances since the 22-15 defeat in Italy in March 2013, as head coach Schmidt hands fringe players the chance to impress.

Jamie Heaslip will captain Ireland, the Leinster number eight and tighthead prop Mike Ross the only frontline stars to start against Warren Gatland's Wales.

Boss Schmidt must submit his final 31-man World Cup squad on August 31, leaving three matches for players to force their way into the reckoning.

Ulster centre Darren Cave has a real chance to impress at 12, in his first appearance since the November walkover against Georgia. Veteran midfielder Gordon D'Arcy is not involved at all despite being fit for action.

Schmidt has given Ulster's Paddy Jackson the nod at fly-half over Leinster's Ian Madigan, with the two facing a potential shoot-out over the last World Cup playmaking berth.

Powerful lock Ryan missed the bulk of last season with a toe injury branded "weird" by Munster boss Anthony Foley.

Now the 31-year-old is finally fully fit, and despite his lengthy Test absence still has a realistic chance of forcing his way into Ireland's final World Cup ranks.

Earls has battled a string of knee and groin problems since his last Ireland foray, and his versatility could work in his favour given the compact nature of World Cup squads.

Ireland: F Jones (Munster), A Trimble (Ulster), K Earls (Munster), D Cave (Ulster), F McFadden (Leinster), P Jackson (Ulster), E Reddan, J McGrath, R Strauss, M Ross (all Leinster), D Ryan (Munster), I Henderson (Ulster), J Murphy, T O'Donnell, J Heaslip (captain, all Leinster).

Replacements: R Best (Ulster), D Kilcoyne (Munster), M Bent (Leinster), D Tuohy, C Henry (both Ulster), K Marmion (Connacht), I Madigan (Leinster), S Zebo (Munster).
