Ulster’s Pro12 home game against bottom club Zebre has been re-arranged for Saturday, 11 March.
The game had to be postponed on 25 November only 90 minutes before the scheduled kick-off because the Kingspan Stadium pitch was frozen.
Ulster will face Zebre in Italy on Sunday, 26 February and then take on the Pro12’s other Italian club Treviso on 3 March at Kingspan Stadium.
Zebre were hammered 70-6 by Leinster at the RDS last weekend.
The bottom club have lost 10 of their 11 games this season, with their sole victory coming away to Edinburgh in late October.
Ulster, after leading the table following five opening wins, have dropped to sixth spot after suffering five defeats in their last seven games.
Overall. Ulster have lost seven of their last 11 games in all competitions.
