The Calgary Stampeders host the BC Lions on Thursday night in a West Division game with plenty at stake for both teams. Calgary enters Week 11 at 4-5 after a narrow 33-30 loss at Toronto, while BC improved to 3-5 with a 27-24 home win over Hamilton. The Lions have already beaten Calgary once this season, winning 41-33 in Kelowna on June 27, but the setting is different this time. Calgary gets home field at McMahon Stadium, Vernon Adams Jr. remains one of the CFL’s most productive quarterbacks, and BC is playing on a short turnaround after Saturday’s game.

- Confidence: 3 out of 5
BC Lions vs Calgary Stampeders Model Projection
- Score Projection: BC Lions 28 – Calgary Stampeders 35
- Win Probability: BC Lions 44%, Calgary Stampeders 56%
BC has already demonstrated that it can move the ball against the Stampeders, and Nathan Rourke’s return gives the Lions a quarterback capable of creating explosive plays from anywhere on the field. Calgary’s ability to force the Lions into longer down-and-distance situations could be decisive, though, particularly if the Stampeders can generate pressure without consistently sending extra defenders. I think the Stamps will do just enough on defense for their lethal offense to create separation late.

BC Lions vs Calgary Stampeders Game Preview
The biggest storyline is the quarterback matchup. Rourke returned from injury for BC’s Week 10 meeting with Hamilton and helped the Lions escape with a 27-24 victory. His 2026 season numbers remain impressive despite the limited sample, with 1,777 yards, 7 touchdowns and 5 interceptions through 6 games.
Rourke’s strongest performance of the season came against Calgary in June. He completed 32 of 42 passes for 462 yards, 3 touchdowns and 1 interception in the 41-33 defeat of the Stampeders. That performance is important for bettors because it shows that BC’s passing game can attack this Calgary defense vertically and create enough explosive plays to keep the Lions competitive even if the running game is inconsistent.
Adams has been just as impressive for Calgary. The veteran quarterback opened the season with 17 completions on 27 attempts for 239 yards and a touchdown against Winnipeg, then threw for 254 yards and a touchdown against Saskatchewan. He followed that with 229 yards and 3 touchdowns on 19 completions against BC in Week 4. His early-season efficiency was especially notable because he had yet to throw an interception through his first 3 games.
Adams then produced one of the CFL’s biggest individual performances of 2026 in Calgary’s 58-36 win over Toronto on July 2. He completed 20 of 25 passes for 405 yards and 6 touchdowns while adding a rushing touchdown. The performance tied Calgary’s single-game record for passing touchdowns and demonstrated the type of ceiling that makes the Stampeders dangerous in a game expected to feature plenty of passing.
BC comes into the game with a little more confidence after finally putting together a win with Rourke back in the lineup. The 27-24 victory over Hamilton was hardly a dominant performance, but it gave the Lions a second consecutive victory over the Tiger-Cats this season and moved BC to 3-5. More importantly for this matchup, Rourke got another game under his belt after missing time, which should help him settle into the offense following his return.
Calgary’s recent form is more difficult to read. The Stampeders crushed Hamilton 44-20 on August 1 before losing a wild 33-30 game at Toronto 5 days later. The victory over Hamilton showed how dangerous this offense can be when Adams gets protection and Calgary establishes its passing game early. The Toronto loss showed the other side of the equation, with turnovers and missed opportunities keeping the Stampeders from converting a strong offensive performance into a road victory.
The first meeting between these teams also provides an important betting clue. Calgary led much of the June contest before BC rallied to win 41-33. Adams played well in that game, while Rourke produced 462 passing yards. That combination suggests Thursday’s game could again be decided by which quarterback makes the most of the opportunities created by the opposing defense. Calgary has the advantage of playing at McMahon this time, which is a meaningful adjustment from the neutral-site setting in Kelowna.
