Leinster backs Robert Kearney and Luke Fitzgerald have been called up to the Irish squad for the September mini-training camp as replacements for Munster duo John Kelly and Anthony Horgan.
Kelly and Horgan have both been forced to withdraw from the three day Ireland get together due to injury.
John Kelly is suffering from an Achilles tendon injury and Anthony Horgan has a hand injury.
Ireland face South Africa, Australia and the Pacific islanders in November.
