Newly-crowned Irish Open Champion Rory McIlroy held a golfing master class with the Northern Ireland squad.
Under the guise of commentator David Feherty, McIlroy provided a demonstration surrounded by the Northern Ireland squad at the K Club.
The 27-year-old also discussed his preparations ahead of hitting the course.
The team are in a pre-Euro 2016 warm-up camp in Dublin ahead of the Belarus friendly on Friday.
Golf's world number three admitted he "felt a little bit shaky" following Sunday's celebrations at the K Club in his Facebook Live broadcast.
While Northern Ireland boss Michael O'Neill said there may be "insurance issues" with his players hitting the driving range.
McIlroy won the Irish Open by three shots over Russell Knox. He shed a tear as he announced he would be donating his £500,000 winnings to his charities.
Northern Ireland face Poland, Ukraine and Germany in France at the European finals.
