Quarterback Vernon Adams Jr. will make his first start for the B.C. Lions on Saturday against the Calgary Stampeders, coach Rick Campbell announced Monday.
Adams, acquired in a trade with the Montreal Alouettes on Aug. 31, will be the club's fourth starting quarterback in as many games.
Star quarterback Nathan Rourke suffered what could be a season-ending foot injury last month before Michael O'Connor suffered a groin injury in the next game.
Antonio Pipkin started in last week's loss in Montreal against the Alouettes with Adams making a short appearance, completing one of three passes for 17 yards.
Adams was Montreal's starter on opening day before losing his job to Trevor Harris early in the season.
The Lions (8-3) have lost both of their games since Rourke's injury and are trying to hold off the Stampeders (8-4) in the race for second in the West.
Adams was a CFL East all-star in 2019 with the Alouettes.
