Bruins president Cam Neely hurled a water bottle against a wall. Boston fans littered the ice with garbage. Coach Bruce Cassidy called it "egregious," in an intense rant about how the quality of playoff officiating has been a "black eye" for the NHL.

The St. Louis Blues won Game 5 of the Stanley Cup Final, 2-1, to take a 3-2 series lead, but it was how they scored that second goal that had the Bruins faithful irate. Moments before David Perron snuck a puck past Tuukka Rask, the officials opted not to call a blatant trip on Bruins forward Noel Acciari by Blues center Tyler Bozak. Acciari hit his head on the ice, taking him out of the play, and eventually put him into the NHL's concussion protocol.
