There is a controversial sequence going around right now involving the Calgary Flames. According to some fans, on the same sequence, several Flames players seem to attack the injured ankle of forward Leon Draisaitl.
The NHL even announced that it would have the Flames on the roster for game number four.
"The league is aware of this clip and the apparent targeting of Leon Draisaitl's ankle. Rest assured that player safety/hockey operations/officials departments are in communication and will be keeping an eye on this for the rest of the series." - Frank Seravalli
