Montreal Alouettes quarterback Antonio Pipkin left Friday's game against the Edmonton Eskimos with an ankle injury.
Pipkin was injured late in the third quarter of the Alouettes' eventual 32-25 loss to the Eskimos.
The 23-year-old was 7-17 for 57 yards and a touchdown through the air, and contributed another 45 yards on five carries at the time of his injury.
Backup QB Vernon Adams Jr. replaced Pipkin and was 7-10 for 134 yards, one touchdown, and one interception.
The Alouettes have a bye week coming up before facing the Hamilton Tiger-Cats in Week 3 on June 28.
