The clip is from a June 25 Irish league match between Waterford United and Mervue United. According to
the match report on Waterford's official website, the goal came in the 53rd minute and was credited to Mervue's Mike Elwood — the unfortunate chap who got smashed in the face. Two more goals were scored after that to give Waterford a 3-0 win, but neither could have been nearly as spectacular.
