Calgary Stampeders quarterback Bo Levi Mitchell left the game against the Lions late in the fourth quarter after favouring his right shoulder.
“I don’t know anything on Bo. It looks like a shoulder, but I don’t know if it was on that throw or if something happened early on. Let’s just instead of speculating without any information we’ll wait and see and go from there,” Stamps head coach Dave Dickenson said after the game.
Backup QB Nick Arbuckle entered the game following consecutive plays where Mitchell threw passes that went incomplete and each time he grabbed his right shoulder in pain. There was no contact on either snap.
The Stamps franchise pivot completed 23-of-34 passes for 252 yards with two touchdowns and one interception during Calgary’s Week 3 game against B.C.
Mitchell played the majority of the 2017 season with tears in his throwing shoulder and elbow issues. That year he managed to throw for 4,700 yards, 23 touchdowns and 11 interceptions while leading Calgary to the best record in the CFL at 13-4-1 despite the ailments.
