It's after Blair Kinghorn sustained an injury in the game against the Brumbies
Naas' Jamie Osborne has been called in to the British and Irish Lions squad.
He was due to be involved with the Irish squad against Portugal this weekend, but Andy Farrell has brought him in as additional cover after Blair Kinghorn picked up an injury yesterday.
The Lions play against an Australian and New Zealand Invitational side on Saturday, with Eadestown's Tadhg Beirne named as captain.
Beirne partners James Ryan in an all-Irish second-row, Hugo Keenan is at full-back with Mack Hansen on the wing.
