Conor McGregor provided inspiration to the Boston Bruins by giving a thunderous pep talk before Saturday night's game against the Columbus Blue Jackets ... kinda surprising given his felony robbery arrest just days before.
Conor was the guest of honor at TD Garden ... check out his roaring speech to the Bruins in the locker room.
The crowd went crazy when Conor came out for a ceremonial puck drop.
During the game, he went crazy with fans and went back into the locker room to congratulate the Bruins on their win.
Earlier in the day, Conor was in Chicago leading the St. Patrick's Day Parade.
