Having defeated Bedford in an attritional fixture last week at Clifton Lane, Rotherham headed over to Ireland on Thursday to give themselves ample time to prepare.
Connaught’s A-team are the club’s representatives in this competition, with their senior side on Heineken Cup duty.
But Rotherham are under no illusions about the size of the task they face, especially as Leinster’s second string won this competition last season.
“It’s their A-team but we know it’s going to be difficult,” said Titans head coach Lee Blackett.
“They didn’t have a great start last week, but they will be smarting and we expect a very tough test at home.
“On their home patch they’ll be roared on by a good crowd and they will be dangerous so we have to be on top of our game.”
Blackett has made seven changes to the team but insists that it remains a competition he wants the club to do well in.
“We’re resting (centre) Juan Pablo Socino because he has a knock, so it’s more precaution than anything else,” said Blackett.
“We want him to be fit for the following week against Scottish.”
