Connacht's postponed Pro14 clash with the Ospreys will take place at the Sportsground on Sunday week.
The game was initially fixed to take place on Saturday 28 November but was called off after a positive Covid-19 test in the Ospreys' squad.
The Westerners, who were beaten by Munster in a pulsating meeting in Galway last weekend, are second in Conference B. The Ospreys game will kick of at 3pm.
Pro14 Rugby also confirmed Scarlets will face Cardiff Blues next Friday night, 8pm.
That game was originally due to be played in February, but both clubs agreed to facilitate an earlier date given the open slot in the calendar.
That slot is available after Europe's final two rounds of group matches were cancelled with the Champions and Challenge Cups moving straight into the knockout phase.
