Winger Simon Zebo has emerged as an injury worry for Ireland after being forced out of training with what appears to be a knee injury.

Zebo was taking part in an open training session in Galway with the Irish squad.

He hobbled off the pitch in apparent pain, after the medical staff had placed an ice pack and bandage on the knee.

Gordon D'Arcy was also helped from the field with an unknown injury, while Isaac Boss also had to end his training session early with a hamstring injury.
