Ireland head coach Joe Schmidt has revealed that Jonathan Sexton has passed his concussion tests and will be fit to face Wales.
Sexton was withdrawn early on during Leinster's defeat to Wasps on Saturday after he suffered a blow to the head.
The Ireland talisman has since come through the concusssion programme and trained with the rest of the Ireland squad at Carton House on Tuesday.
"Johnny trained very well. He’s fully fit and has passed all three HIA tests," Schmidt said at the Six Nations launch on Wednesday.
"As far as Johnny is concerned he’s ready to go in 11 days time.
"We try to treat any head injury with the respect it needs to be dealt with. It wasn’t a significant game [against Wasps] and therefore they identified some important games were coming up for Johnny, which has fallen to our advantage because he’ll be fully fit to go.
"All we can do is go on the best medical opinion. The best medical guys, when they give them the all clear we have a lot of trust in them.
"They’re the experts and if people question that then again, it’s always a disappointment, but it’s also a reality because no one is going to have the same opinion necessarily, but you try to get the opinions from those best qualified, to not put anyone at risk.
"He trained really well yesterday. There was no contact training – apart from the wind – but he’s good to go."
