Munster's European Rugby Champions Cup match against Stade Francais has been postponed.
The match was originally due to take place at the Stade Jean-Bouin in Paris on Sunday, but will be rearranged after advice from police.
Both clubs have agreed that police resources should be diverted elsewhere, following the terrorist attacks in Paris last week.
At least 129 people died in a series of attacks across the city, including an attempted bombing at the Stade de France.
Ligue 1 fixtures are due to go ahead as normal across France this weekend.
