Ireland centre Gordon D'Arcy was given the green light to take his place alongside Brian O'Driscoll as the Leinster pair chase their fifth Triple Crown against Scotland in tomorrow's Croke Park farewell.
However, D'Arcy will continue to be monitored by the Ireland medical team to ensure there is no reaction.
“A final decision on his availability and fitness for the game will be made following the final run out in Croke Park,” said an IRFU spokesman.
Irish defence coach Les Kiss claims that Ireland can bounce back from the disappointment of losing what was almost certainly their championship decider in Paris last month.
“Once that's happened we had to move forward and I think to date the team have,” said Kiss. “The Triple Crown is important for us, obviously the Grand Slam is gone. That's over. For us, there are other things to get on track and now we need to put together a good end to the campaign. We want to win the Triple Crown.
“We think it's in the capacity of this team to go into every Test and believe we can win every Test. It's critical to us to get this game right and we want to make sure that we can get the performance and do the best we can.
“If we get the training right and we do the things we can do, we know we can come out the back end of most games.
“Winning is a habit and when it comes to those tight matches, we've proven that we can eke it out through a variety of ways to win games.”
