Ulster centre Stuart McCloskey has been called up to Ireland's squad for the Six Nations.

Initially omitted from Andy Farrell's 35-man panel, McCloskey was added to the group ahead of a training camp in Portugal.

His inclusion comes after Chris Farrell missed Munster's Champions Cup win over Ospreys, the centre ruled out because of a knee injury.

"Stu has been playing well over the past few weeks," Andy Farrell said.

"Centre is a very competitive area in the squad and with a few backs picking up small niggles at the weekend, Stu is the form back who will now be added to the group to give us some extra options."
