The Montreal Alouettes have filed an official protest with the Canadian Football League concerning a controversial play that cost them a touchdown in a 19-12 loss to the B.C. Lions in a game last Friday at B.C. Place, Sportsnet.ca has learned.

As per CFL rules, teams have until 72 hours from the start of a game to file a protest. As first reported by Sportsnet on Sunday, Als management discussed filing a protest and followed through with it.

The incident that has ignited the protest stems from a touchdown called back because the play had, according to the officials, been negated when a whistle had been blown prior to or just after the play started.

The game supervisor and video replay official were under the impression the time remaining in the game should have been 1:05 instead of 1:00 and buzzed the on-field officials to stop the play to clarify the official time. CFL director of officiating Tom Higgins has admitted a mistake was made by the league pertaining to the time -- it was, in fact, one minute to go -- but that a whistle had definitely been blown on the play. The Als are disputing that.

"We just want what is right," Als general manager Jim Popp told Sportsnet.ca.

The matter will now be discussed by the league office and could result in a ruling by commissioner Mark Cohon. It will likely have to be ruled on in the next few days because the two teams play this Sunday in Montreal.
