The Welsh Rugby Team are obviously in Dublin this weekend for the match.
They were staying in a Kilmainham Hotel for the duration of their stay and en route to the Aviva today, their coach Warren Gatland, decided they could benefit from a last minute, impromptu training session.
A local caught all the action though according to The Independent, he was asked not to film any of the activity.
“It was definitely them, I saw from outside the house,” he told The Independent.
“I was talking to one of the coaches, to one of the younger ones. They just told me not to film what they were doing.”
The Match kicks off at 3pm and you can watch it on ITV or BBC.
