Broadcast: TSN / RDS2 / CFL+
Venue & Game Setting
McMahon Stadium — Calgary, AB A 35,000‑seat outdoor venue known for early‑season cool temperatures, swirling winds, and a notoriously firm playing surface. Calgary’s home‑field advantage is historically strong in June due to altitude, wind patterns, and the Stampeders’ comfort with the stadium’s unique turf bounce.
Weather Forecast (as of game‑day morning)
Temperature: 58–61°F (14–16°C) at kickoff
Conditions: Clear skies, dry air
Wind: 10–14 mph from the northwest — favors cross‑field gusts that can disrupt deep passing
Humidity: Low (30–35%)
Precipitation: <5%
Impact: Slight boost to the kicking game due to dry air; passing efficiency may dip on longer throws; run‑game stability becomes more valuable.

Recent Team Form (Preseason & Camp Notes)
Winnipeg
Collaros looked sharp in limited preseason reps
Oliveira’s health is the biggest storyline; backups showed competence but not star‑level burst
Defense appears fast and cohesive, especially in the linebacking corps
Calgary
Maier showed improved decision‑making and quicker reads
Mills looked explosive and decisive in preseason action
Secondary communication issues remain a concern, especially with Roberson out
Key Player Matchups
1. Zach Collaros (WPG) vs. Calgary Pass Defense
With Schoen out, Collaros must rely on Nic Demski and Kenny Lawler to generate separation. Calgary’s weakened secondary could be vulnerable to Winnipeg’s layered route concepts.
2. Brady Oliveira (WPG) vs. Calgary Front Seven
If Oliveira plays, Winnipeg’s offense becomes significantly more balanced. Calgary must win early downs to force Collaros into predictable passing situations.
3. Reggie Begelton (CGY, if active) vs. Demerio Houston (WPG)
Begelton is Calgary’s most reliable chain‑mover. Houston’s ball‑hawking ability makes this a high‑leverage matchup.
4. Winnipeg OL vs. Calgary DL
Stanley Bryant anchors a veteran unit, but Calgary’s interior pressure—led by Mike Rose—could disrupt timing if they win early.
