While everyone else is out drinking green beer and eating their corned beef hash, these fighters are hard at work perfecting their crafts. They all have put in many hours training their respective combat sports to become world class athletes. So instead of looking for someone not wearing green to pinch, we decided to hunt down seven of our favorite Irish fighters (in no particular order).
Conor McGregor - MMA
We had to get #ConorMcGregor out of the way first as he's probably the first person we all thought of when we read 'Irish fighter.' He's the biggest star in the UFC right now and easily becoming a household name.
Stats: Conor was the first ever #UFC champion to hold a belt in two different weight classes simultaneously. His current professional record is 21-3.
Katie Taylor - Boxing
Katie Taylor can be compared to #RondaRousey in that due to her popularity women's boxing was more widely recognized and respected and not just in Ireland. Not only did she compete (and excel) in the sport, but she also competed in association football. She's one tough chick.

Stats: Bowe is a seven-time world and European medalist and a five-time Abu Dhabi World Pro Black Belt Trial winner.
James Gallagher - MMA
You can't be an Irish MMA fighter without being constantly compared to Conor McGregor and James Gallagher is no different. He's currently fighting under the Bellator banner.
