All the talk has been of the Montreal Alouettes offence this season, but now the defence can stand as tall as any quarterback or receiver.The Alouettes defence did not give up a touchdown for a second consecutive game as Montreal downed the injury-riddled Saskatchewan Roughriders 37-12 in a hard-hitting CFL matchup on Sunday afternoon at Percival Molson Stadium.With the win, Montreal (9-4) officially clinched a playoff berth, ended a run of four straight losses to the Roughriders (8-5) and handed Saskatchewan its first loss to an East Division club in six games this season.
