The Ireland A team to play France A at Ravenhill on Friday night shows three changes from the team that beat Italy A 10 days ago.
The second string are unbeaten this season after a draw in Scotland and victory in Rogivo on February 21st.
But coach Matt Williams will have a new prop for his front row at Ravenhill as a result of the injury to Reggie Corrigan.
Marcus Horan has been promoted as Corrigan's replacement in the first XV and the vacancy he left on the replacements' bench will be filled by Ulster's Justin Fitzpatrick, meaning Connacht's Ronan McCormack comes into the A side.
Similarly, Ronan O'Gara's recovery from an ankle injury means Harlequins' fly-half Paul Burke drops back down to the A side with London Irish's Barry Everitt demoted to the bench.
There is also a positional change with Jeremy Staunton to be tried at outside centre after Gordon D'Arcy played the first two A internationals of the season in the number 13 shirt.
D'Arcy takes over Staunton's full-back role as the Irish management continue their search for a genuine understudy at outside centre for Brian O'Driscoll.
