The Ireland A team features several fresh faces for this Friday's clash with England A at Donnybrook.
Lock Donncha O'Callaghan returns to the A team having played the final 10 minutes of Ireland's dramatic RBS 6 Nations victory over Wales in Cardiff on Saturday, an indication that Gary Longwell is fit and ready to return to the senior squad after missing out at the weekend due to hamstring injury.
O'Callaghan partners captain Jeremy Davidson in the second row, while also coming into the team are fit-again wing Tyrone Howe and front row Emmet Byrne while Munster wing Anthony Horgan is drafted in on the replacements' bench, all for their first tastes of international rugby this season.
With Ulster's Neil Doak suffering from a shoulder injury and Harlequins' Paul Burke out with groin problems, Ireland A coach Matt Williams has a new half-back partnership to face the English second string with London Irish fly-half Barry Everitt and Leinster scrum-half Brian O'Meara moving up from the replacements' bench.
Also missing through injury are Munster duo Rob Henderson (ankle) and Jeremy Staunton (groin) leaving Connacht's Gavin Duffy and Leinster's David Quinlan free to form the Ireland A midfield.
