Sonny Bill Williams attended an U13s training session on Wednesday night and offered some advice to the stunned youngsters.
The New Zealand great turned boxer was a guest at Seapoint Rugby Club in Dublin and took time to speak to the young players and their coaches.
The visit came as a bit of a surprise to those at the club after a parent arranged the visit, but Williams was brilliant with the children as he discussed all things rugby.
Williams is currently in Ireland to train with Andy Lee for his next fight, which is set to take place in March.
The 36-year-old helped fellow countryman Joseph Parker to prepare for his win over Derek Chisora before Christmas and trained with world heavyweight champion Tyson Fury in recent weeks.
