Ulster hooker Rob Herring says the team are determined to regroup from the disappointing defeat in Edinburgh in Friday's home game against Cardiff Blues.
Herring insists that there was no lack of effort in last weekend's disappointing 16-10 defeat at Murrayfield.
"We were just making small errors, with stuff like knock-ons in their 22," said Ireland international Herring.
BBC Sport NI's weekly online programme featured highlights of last weekend's defeat while Ulster's South African player Franco van der Merwe insists that the gap between the Southern Hemisphere heavyweights and Europe' top nations is "not as big as some people are making out" following last weekend's World Cup quarter-finals results.
