MONTREAL - Jonathan Crompton threw three touchdown passes as the Montreal Alouettes downed the Saskatchewan Roughriders 40-9 on a Monday afternoon marked by quarterback great Anthony Calvillo's jersey retirement.

Crompton hit Duran Carter with a pair of TD tosses and Brandon London with another. Back-up quarterback Tanner Marsh also scored as Montreal (6-8) won a third straight game. The Alouettes are 5-1 since Crompton took over as the starter. Sean Whyte added four field goals. Anthony Allen caught a TD pass from Tino Sunseri for the Roughriders (9-6), who lost a third game in a row. Saskatchewan, struggling without starting quarterback Darian Durant, has lost four of its last five games.

The Riders missed a chance to clinch a playoff spot, while Montreal joined Toronto and Hamilton atop the East Division with six wins.

Calvillo, the CFL's all-time passing leader who retired in January, got a standing ovation from the season-high crowd of 23,069 as he had his No. 13 jersey retired in a halftime ceremony attended by former teammates, including his mentor Tracy Ham.

The Roughriders controlled the ball early as Allen ran the ball repeatedly, but it took an Alouettes turnover to set up the first score as Tristan Jackson recovered Carter's fumble at the Montreal 35. Five plays later, Sunseri hit Allen with an 11-yard TD pass.
