The Canadian Football League has suspended a Toronto Argonauts executive indefinitely after he was seen slapping a Hamilton Tiger-Cats fan and accused of using a homophobic slur following Sunday's playoff defeat.

Video of the incident went viral, showing Argos vice president of player personnel John Murphy getting into a post-game altercation with both male and female fans as Toronto players walked to their locker room. 

According to several reports, the skirmish began after a Hamilton fan spit beer at an Argonauts player.  

The video that circulated on Twitter showed Ontario police apprehending someone while a man, believed to be Murphy, is seen yelling at a female TiCats fan.

The situation escalated when a Hamilton fan on the opposite side of the fenced-off walkway screamed and gestured towards Murphy, who responded by slapping the man's arm.

In return, the man tried slapping Murphy before flipping off the Argos vice president.

Murphy attempted to slap the man again before he was pulled away by security.  

'The Canadian Football League has suspended indefinitely John Murphy, Toronto Argonaut Vice President [of] Player Personnel, following an investigation into his physical and verbal altercation with fans following last Sunday's Eastern Final,' read the league statement.

The CFL is also investigating other 'player altercations with fans' from that game after another video went viral, showing spectators attacking the Argos.

That video shows a Hamilton fan shoving Toronto defensive back Chris Edwards on the stadium's lower concourse. Edwards then took a swing at the fan, who was wearing a TiCats flag as a cape.

The fan continued to pursue Edwards, but was met by Argos receiver Dejon Brisset, who pushed him against a wall as security intervened and apprehended the man.

Hamilton beat Toronto, 27-19, to advance to the Grey Cup, the CFL's title game, on Sunday against the Winnipeg Blue Bombers.
