Conor Murray says he "got a bit of a scare" during Ireland's defeat to England at Twickenham on Saturday but is now feeling "good".
The Ireland scrum-half left the pitch just after the half-hour mark for a Head Injury Assessment following a clash with England winger Johnny May.
"[I] Just got the head on the wrong side of a tackle," said Murray at the launch of the Aviva Mini Rugby Nations Cup.
"For me, it's a work-on, getting my head and feet right, but it's tough in the wider channels when you think that someone like Johnny May is really quick, you don't want to get beaten on the outside and then he steps back inside.
"I just got a bit of a bang and then passed everything, passed HIA and that stuff. I trained fully Monday and Tuesday."

Murray actually came back onto the pitch with two minutes of the first half remaining. Joe Schmidt later said that had been due to a breakdown in communication. He was replaced permanently by Luke McGrath after the break.
Then at half-time, I still wore the bang a bit and we all decided together that had it been a more important match [I would have stayed on]. I'm not saying a test match against England isn't important - it was just wiser to take the precaution and not come back on.
It was a big enough impact. Maybe it was wiser to take your beating and then come back and fight another day.
Murray, who said there was no element of an elbow from May in the tackle, added that first thought was to worry about his prospects of travelling to next month's World Cup in Japan.
"Yeah, that's just the natural thing in my head, and anyone who gets a bang between now and when the plane sets off - you're going to be worried about it. It's such a big thing."
