Ireland head coach Andy Farrell was delighted to get a "physical" hit out against Ulster yesterday as both sets of players were put through their paces in training.
Like Ireland, Ulster have been impacted by the ongoing coronavirus problem as their PRO14 clash against Benetton was postponed last week, while Munster's trip to Treviso (March 21) and Connacht's game in Zebre (March 28) have also succumbed to the same fate.
With no game to prepare for this weekend, Farrell decided to invite Ulster, who included internationals Jordi Murphy, Luke Marshall and Craig Gilroy, as well as Robert Baloucoune, who was named as a development player in Farrell's initial Six Nations squad.
"Ulster have come down and we were unbelievably grateful that they took the time to come to the High Performance Centre and have a great outing against the boys," Farrell said.
"It was a great session that was done in the right manner. It was pretty physical at times but done in the right manner and both sides got a lot out of it. We really appreciate them coming down."
Ulster captain Iain Henderson, who trained against his province, also welcomed the session: "Ulster really lifted the intensity of training. A bit of competition coming into training, it was exactly what both sides needed."
