The illness that kept Chris Henry out of Saturday's win over South Africa is still being investigated.

Management have confirmed that he is healing well but could not play due to a severe migraine among other symptoms before last weekend's game.

Jared Payne's foot injury is undergoing further scans tomorrow while Rory Best has commenced light running and his prognosis is positive although he will likely be held for the game against the Wallabies the weekend after next.

Darren Cave, Andrew Conway , Robin Copeland and Tadhg Furlong have all been added to the squad for training purposes ahead of Sunday's game with Georgia.
