Munster 'A' will face English Championship outfit Doncaster Knights in the quarter-finals of the B&I Cup on Saturday, January 24 at Castle Park (2.0).
Mick O'Driscoll's men only qualified for the knockout phase thanks to a dramatic bonus point 35-13 victory away to Moseley on the final day which left them as one of the best three runners-up in the competition.
Worcester Warriors topped Pool 3 with wins at home and away against Munster to deny the Reds a more favourable quarter-final slot.
Indeed Worcester, Doncaster and Bristol are the only sides to have completed a clean sweep from their fixtures.
The Knights have the best record heading into what is only their second appearance at this stage of the competition.
Although sitting 11th in the English Championship they won all of their pool games and only missed out on one four-try bonus point, away to Bedford Blues.
It will be Munster A's fifth appearance in the quarter-finals and they will be looking to prove themselves after the losses in Rounds 2 and 5.
Captain Jack O'Donoghue has starred throughout the campaign but it will difficult against a side that have accumulated 29 tries in six games so far.
This is the sixth season of the competition and the title has been kept in Ireland for the past two seasons.
Leinster became the first side to win it twice when they defeated Leeds Carnegie last year, with Munster taking the crown in 2012 when they beat Cross Keys.
