Torey Krug's crushing hit on Blues forward Robert Thomas was the most memorable moment from Game 1 of the 2019 Stanley Cup Final, but before that play, the Bruins defenseman had a lengthy tussle with St. Louis forward David Perron in front of the Boston net.

These players traded jabs, pushed each other around and Perron even took off Krug's helmet. When both of them got up, Perron was done with Krug and skated toward the Blues bench. Krug wasn't able to retaliate with Perron as a result and instead took out his frustration on Thomas at the other end of the ice.

Bruins goalie Tuukka Rask had a front row seat to the Krug/Perron exchange, and he had a great reaction to the incident when asked about it Tuesday.

Here's a look at the incident between Krug and Perron:

It wouldn't be surprising if Krug and Perron revisit their Game 1 fisticuffs at some point during Wednesday night's Game 2 at TD Garden. Game 1 was a physical affair and the rest of the series should follow suit considering these are two big, physical teams. 

Perron and the Blues need to be smart, though, because they were undisciplined in the series opener and put the Bruins on the power play five times. Boston's power play is converting at an impressive 34.5 percent rate during the team's eight-game playoff win streak, including one goal Monday night, so St. Louis needs to walk a fine line between being physical and staying out of the penalty box.
