VANCOUVER -- Kevin Glenn threw for three touchdown passes as the Calgary Stampeders upset the B.C. Lions 34-29 in the CFL West final on Sunday before a disappointed crowd of 43,216 at B.C. Place Stadium.

The Stampeders, who finished second in the West Division behind B.C. during the regular season, will play the Argonauts in the Grey Cup next Sunday in Toronto.

The loss denied the Lions a second straight Grey Cup.

Marquay McDaniel, Maurice Price and Romby Bryant caught Glenn's touchdown passes. Backup quarterback Bo Levi Mitchell ran for another TD, while kicker Rene Paredes supplied the rest of Calgary's points.

Lions defensive back Korey Banks, on an interception, and receiver Nick Moore on a last minute reception, scored touchdowns for the hosts.

Paul McCallum provided B.C.'s other points by kicking five field goals.
