Ulster back-row Sean Reidy admits it's "all or nothing" when his team returns to PRO12 duty against the Ospreys at the end of the month.
Following a 22-20 loss at the hands of Munster at Thomond Park over the weekend, Ulster have until May 29 to wait until their next game.
Reflecting on their defeat in Limerick, Reidy admitted it was "bitterly disappointing" to go down to their rivals as they remain in fifth place.
"It is disappointing that we didn't finish off a few of our green zone efforts," the back-row told Ulster's official website after their away loss.
"We just had too many knock-ons at critical times and it let them back into the game. We have to cut out the handling errors, especially against sides as good as Munster."
Looking ahead to their trip to Swansea, he added: "We have Ospreys over there and it's going to be a very tough game, so we'll prepare for that accordingly.
"Ospreys have been playing some pretty good footy all year, it's just in the last few weeks that they've had a few slip ups.
"We know what they're like over there and we're not going to take it lightly – it's all or nothing! You've got to roll with the punches."
