Munster 'A' make a difficult trip to Castle Park tomorrow to take on Doncaster Knights in the quarter-final of the of the B&I Cup (2pm).
The English Championship club have dominated this season's competition - despite being 11th in their league standings the Knights are one of the form teams in the B&I Cup.
Along with Bristol and Worcester, they are the only teams to have won all of their pool games - with Doncaster leading the overall points tally on 29 out of 30.
The Knights won six from six in Pool 4, beating Bedford Blues, Cornish Pirates and Cross Keys home and away - the only time they failed to pick up a bonus point was in their 17-15 defeat of Bedford in November.
However, their Championship form is in stark contrast to what they have produced in the B&I Cup.
A 26-19 home defeat to Jersey last weekend was their eighth straight loss in the league - their last victory came against Yorkshire Carnegie at the end of September.
Munster 'A' won four of their six pool games - their defeats at home and away to Worcester Warriors meant they couldn't qualify top of Pool 3.
It will be their fourth trip to England this term after victories away to Moseley and Nottingham and that 27-23 loss to Worcester at Sixways in Round 2.
