GAME NOTES: The Winnipeg Blue Bombers will have a rookie handling their punting chores in this game due to a most bizarre off-field accident. When the Bombers released veteran punter-kicker Troy Westwood, they brought in Duncan O'Mahony to do their punting. But O'Mahony has a broken toe, courtesy of stubbing it late Sunday night while en route to the bathroom. That means rookie kicker Alexis Serna will handle the punting chores as well. This game is a rematch of last year's East Division final, won 19-9 by Winnipeg. But the Bombers effectively lost the Grey Cup as a result of this victory as quarterback Kevin Glenn suffered a broken left arm, forcing Ryan Dinwiddie to make his first CFL start in the league's championship game. Dinwiddie threw three interceptions as Saskatchewan beat the Bombers 23-19. Glenn is back healthy for Winnipeg after leading the CFL in passing last year. But the Bombers will have to make due without all-star receiver Milt Stegall, who continues to recover from offseason knee surgery. That still leaves the club with two 1,000-yard receivers in Terrence Edwards and Derick Armstrong. Once again, a focal point of the offense will be running back Charles Roberts. Roberts was second in CFL rushing last year with 1,379 yards and averaged more than five yards a carry while scoring 16 touchdowns. The offensive line was bolstered by the return of tackle Dan Goodspeed and guard Matt Sheridan. Goodspeed re-signed before becoming a free agent while Sheridan elected to return to Winnipeg after being granted free agency. Longtime Argos defensive coordinator Rich Stubler makes his CFL head coaching debut. Stubler takes over from Mike Clemons, who is now the club's chief executive officer. Quarterback Kerry Joseph also makes his Toronto debut. Joseph was the CFL's outstanding player last year and helped Saskatchewan win the Grey Cup. But he was dealt to the Argos in the offseason. The numbers: Winnipeg was tied with B.C. for the best home record in the CFL last year at 7-2 and was 7-3 within the East Division. Toronto was 5-4 on the road and 7-3 versus conference rivals. Keys to the game: This could be a low-scoring affair given that both teams are very good defensively. Toronto had the CFL's best defense last year in terms of fewest yards allowed (306 per game) and fewest points allowed (15.9). That's worth noting because the Argos have just one newcomer on this unit, that being cornerback Willie Middlebrooks, a former NFL first-round pick. Middlebrooks will take over from cornerback Jordan Younger, who was traded to Edmonton. End Jonathan Brown was second in the CFL in sacks with 13. Winnipeg counters with unit that finished second in the CFL in yards allowed (328 per game), third in the CFL last year in sacks (50) and fourth in points allowed (21.3 per game). Rush end Tom Canada, another free agent who re-signed with the Bombers in the offseason, was tied for third in the league with 12 sacks. Also, linebacker Barrin Simpson was second overall in tackles with 112. However, if there's a spot where Toronto would appear to have an edge it's on special teams with the offseason return of Mike Vanderjagt. Vanderjagt helped Toronto win Grey Cups in 1996 and '97 before heading to the NFL, where over nine seasons he became the most accurate kicker in league history. Still, there's something about playing at home that brings out the best in the Bombers.
