The Calgary Stampeders expect to be without starting quarterback Drew Tate for more than a month.
Coach John Hufnagel estimates that Tate will be out for five or six weeks with a left shoulder injury.
He said Tate had an MRI exam on the shoulder and is getting an opinion from a second doctor before a definitive diagnosis is made.
Tate was injured during a 39-26 loss in Toronto on Saturday.
Veteran Kevin Glenn will take over and will start against the Alouettes in Montreal on Thursday night.
The Stampeders acquired Glenn in an off-season trade that sent Henry Burris to the Hamilton Tiger-Cats.
