Ireland coach Declan Kidney has called up Sean Cronin to the squad for the upcoming Guinness Series of games against South Africa, Fiji and Argentina.

With several players picking up knocks over the weekend, Kidney has added seven players to the initial 31-man Ireland training squad.

The injury of most concern was to Ireland captain Brian O'Driscoll who sprained his ankle in Leinster's clash with Cardiff Blues at the RDS on Saturday.

After undergoing a scan on the injury today, it was revealed that the damage was less severe than anticipated and his progress will be monitored.

As a result, four extra backs have been added to the squad with uncapped Ulster trio Craig Gilroy, Paddy Jackson and Paul Marshall joining Connacht wing Tiernan O’Halloran, who is also upcapped, in the Ireland camp.

Cronin’s inclusion is a result of Rory Best taking a knock in the Dragons game over the weekend, while Declan Fitzpatrick played for Ulster at the weekend and will join the camp along with tight head prop Michael Bent, who is Ireland qualified through his maternal grandmother and has been playing regularly for Taranki in the provincial championship in New Zealand.

Bent arrived in Dublin today and will link up with the Ireland squad for training tomorrow.
