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

The 27-year-old had not been included in the panel initially named by head coach Andy Farrell last Wednesday.

He had included Garry Ringrose, Bundee Aki, Chris Farrell and Robbie Henshaw among the primary options to fill the two centre roles.

But Farrell has now made the decision to draft in McCloskey, citing "small niggles" to the backs in the original selection.

"Stu has been playing well over the past few weeks and played well again at the weekend," he 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." 

McCloskey has three Ireland caps to date, having made his senior debut in 2016. He has made 11 appearances for Ulster in the 2019-20 season, scoring two tries.
