Ulster’s opening European Champions Cup game in Oyonnax, France, which was due to take place on Saturday afternoon was postponed following the tragic events in Paris on Friday night.
It followed the postponement in Paris of Racing 92 against Glasgow Warriors.
Tournament organisers also confirmed that all European Champions Cup and Challenge Cup games due to be played in France this weekend were postponed.
Ulster Rugby confirmed on their Twitter account that the game was postponed and said later in a statement on their website: “Due to the tragic events last night in Paris and the current period of national mourning in France, EPCR has decided to postpone this weekend’s European Rugby Champions Cup and Challenge Cup matches scheduled to be played in France.
“Therefore, today’s game between Oyonnax and Ulster Rugby has been postponed and will be rescheduled for a later date. We will provide updates on the situation as soon as they become available.

Meanwhile, Northern Ireland’s Under-21 side flew out of Paris on Friday afternoon following a game against France.
Irish Football Association chief executive Patrick Nelson told Press Association Sport: “Firstly we were shocked, as everyone will be. We heard about it midway through the second half of our match (against Latvia) and saw the news unfolding. Our thoughts, sympathy and prayers are with everybody who has been caught up in the incidents in Paris.”
European football’s governing body UEFA issued a short statement on Saturday morning which read: ‘’UEFA is deeply shocked and saddened by the tragic events which occurred in Paris last night and wishes to express its support and solidarity to France and to those affected by these horrible acts.”
