The Stanley Cup Playoffs are one of the most unique events in all of sports in that these teams can compete against each other and leave their literal blood, sweat, puke and tears on the ice for seven games, and, when it's all said and done, will meet at center ice to shake hands and congratulate one another on a hard-fought series.

While there are plenty of displays of sportsmanship after the final buzzer sounds, that doesn't mean relations are all that warm and fuzzy during the games.

That was on display in Game 6 of a first-round series between the Buffalo Sabres and Boston Bruins Friday night.

As time was winding down in the third period and the Sabres nursing a 4-1 lead, it looked as though the Bruins were headed towards another quiet, disappointing early exit in the Stanley Cup Playoffs.

As the Sabres dumped the puck in deep to try and slot home another empty net goal, that's when all hell broke loose.

Buffalo's Zach Benson and Boston's Charlie McAvoy chased the puck into the zone and, while battling for position, Benson "slew-footed" McAvoy, causing the latter to lose his balance and go crashing into the boards.

What McAvoy did next can only be described as "assault."

That kind of swing would get you 5-10 in a state penitentiary if you tried it on the streets.

What in the world is McAvoy thinking there?
