A National Lacrosse League player snapped on some hecklers following a game over the weekend -- attacking the fans with his fist before swinging his stick at them ... and the wild incident was all captured on video.
The scene unfolded at the end of the Halifax Thunderbirds' loss to the Colorado Mammoth in Denver.
In footage shot by a spectator in the stands ... you can see as Halifax's players were walking toward their locker room, several fans seemed to throw insults their way.
