Ireland have called up seven new players to their squad for the November internationals.
Four backs and three forwards have been added as cover after a series of injury scares over the weekend.
Brian O'Driscoll was among those hurt, turning his ankle during Leinster's victory over Cardiff, and although the captain is expected to be fit the Irish management is erring on the side of caution.
Ulster backs Craig Gilroy, Paddy Jackson and Paul Marshall are all called up along with Connacht winger Tiernan O'Halloran.
And Leinster duo Sean Cronin and Michael Bent will cover the pack along with Ulster prop Declan Fitzpatrick.
Ireland start their November series against South Africa in Dublin on 10 November before playing Argentina two weeks later.
