Caelan Doris urged Ireland to pick themselves up off the canvas quickly after a "gutting" Grand Slam-busting defeat to England at Twickenham.
Marcus Smith won it for the hosts with the last boot of the ball as his drop-goal snatched a dramatic 23-22 win.
It ended Ireland's dreams of back-to-back Slams, though they can still win the Championship title if they get past Scotland at the Aviva Stadium next Saturday.
"Gutting the way it finished," he told RTÉ Sport. "It was a proper Test match, back and forward throughout.
"We definitely didn't underestimate them, we’ve seen what they are capable of. We saw how well they went in the World Cup, coming third. We're disappointed with aspects of our game throughout.
"They put us under pressure which explains some of it, but some of it was in our control, definitely."
The Scots' earlier defeat to Italy meant any win would have seen Ireland clinch the title. It wasn't to be, however if Andy Farrell's men can finish their campaign with a win in Dublin in a week's time, they will win the championship.
That would ease the pain of their Twickenham heartache - and Doris is confident the squad can bounce back.
"They put us under pressure...they fired a lot of shots in the first half and kept going in the second half..." - Caelan Doris reacts to Ireland's 23-22 loss to England at Twickeham.

"It’s a big week ahead," he added. "There’s still a lot at stake next week, we’re going to have to dust ourselves down quickly and get excited for that.
"We were pretty content going into half-time, being up the couple of points but they just kept going the second half. We had a few purple patches where we got on top but they kept battling through and it came down to the last minute.
"We’ve a lot of belief in what we do. We respected them all week and knew what they were capable of, and they showed us today.
"[We're] massively excited to be back in the Aviva, playing Scotland who have gone well in the championship. Big game to finish off, hopefully we can finish on a good note."
Josh van der Flier echoed those sentiments, lamenting Ireland's failure to grab the contest by the scruff of the neck.
"It was in our control," he said. "There's certainly things we could have done a lot better, especially towards the end of the game and throughout I suppose. That's probably the overriding feeling, disappointment.
"It's heartbreaking really to lose that way. I suppose it's what makes sport so great. We've definitely been on the right end of a lot of those over the years, so full credit to England. I thought they were brilliant in fairness."
