Tadhg Furlong says he is still on course to play in Ireland's Six Nations opener in Cardiff in just over a fortnight's time.
Furlong has been dogged with injuries since rolling his ankle prior to the victory over South Africa in November - he still started all three Autumn series wins - but having also had to deal with hamstring and calf injuries in recent weeks.
He suffered the calf problem just as he was about to make his comeback at the start of the month.
