MONTREAL -- Montreal Alouettes quarterback Anthony Calvillo is scheduled to undergo further testing Monday after suffering a suspected concussion Saturday against the Saskatchewan Roughriders.
Calvillo was injured in the first half of Saskatchewan's 24-21 home win after being taken down hard by Roughriders defensive end Ricky Foley.
Calvillo didn't return and was replaced by backup Josh Neiswander, who finished 12-of-30 passing for 147 yards and two interceptions in his CFL debut.
The Alouettes said in a statement test results should be known by Tuesday.
Montreal (2-5) hosts the B.C. Lions (5-2) on Thursday night.
Calvillo won't be the only injured Alouette to undergo testing.
According to the Alouettes, also scheduled to visit the doctor's office are linebackers Bryn Roy (knee), Jonathan Beaulieu-Richard (ankle) and Kyries Hebert (knee), long-snapper Martin Bedard (shoulder), tackle Josh Bourke (knee), safety Mike Edem (shoulder) and receiver Brandon London (head).
