The Saskatchewan Roughriders mistakes cost them in a 28-17 loss to the Montreal Alouettes.

The Riders took 200 yards in penalties, missed two field goals and were intercepted twice in the fourth quarter.

Rookie quarterback Drew Willy didn't get much help in his first start as a pro, but he also failed to move the ball with good field position numerous times during the game.

The Alouettes got off to a quick start, scoring touchdowns on their first two possessions and a 14-3 lead. The Alouettes also scored at the end of the first half to take a 22-6 lead into the locker room in what looked like a potential run away for Montreal.

The Riders defense rallied early in the third quarter to hold Montreal deep in their own end. The Alouettes conceded back to back safeties to make the game 22-10.

Saskatchewan's Sandro DeAngelis had field goals of 48 and 43 yards in the third but missed them both and got no points to show for it.

Drew Willy would eventually get the Riders on the board with a touchdown. Early in the fourth quarter he found Kory Sheets on a dump pass and Sheets snuck his way to the end zone for the 35-yard score. The Riders found themselves down by five with 14 minutes to go but than penalties cost them again.

Twice, the Riders had the Montreal Alouettes ready to punt but took penalties to extend drives. Sean Whyte made two late field goals to finish the scoring as the Alouettes moved to the top of the East Division with a 7-4 record. The Riders are once again tied for third in the West with a record of 5-6.

Next up for the Riders is a battle against the Calgary Stampeders, who have won four straight.
