The decision has been made due to the severe weather warning in place and the dangerous wind conditions expected to occur across Scotland and Glasgow this Friday - the original date for the fixture.
Safety of spectators, team and venue staff, players, match officials and broadcast personnel are the number one priority and it is clear that the expected weather conditions would severely compromise this.
The URC would like to thank both teams involved, the host broadcaster Premier Sports and the Irish broadcaster TG4, for their understanding in rearranging this fixture to ensure it takes place on a scheduled weekend.
All Season Tickets and Match Tickets remain valid for the rescheduled date and kick-off time.
Fans watching the game in the Republic of Ireland will only be able to view the game on the TG4 player.
The Glasgow Warriors v Clovers match in the Celtic Challenge remains scheduled for Saturday 25 January, kick-off 1.00pm.
