REGINA -- The Montreal Alouettes provided an update on the status of injured quarterback Anthony Calvillo on Monday, saying the veteran will undergo further medical testing throughout the day.
His results - along with seven other injured Alouettes - should be known by Tuesday.
Calvillo (head), Brandon London (head), Kyries Hebert (knee), Josh Bourke (knee), Mike Edem (shoulde), Martin Bedard (shoulder), Bryn Roy (knee) and Jonathan Beaulieu-Richard (ankle) were all injured in Saturday's loss to the Saskatchewan Roughriders.
Calvillo left the Week 8 clash after taking a hit from defensive end Ricky Foley.
Trailing 7-3, the Alouettes had moved from their own 37-yard line to Saskatchewan's 37 when Calvillo went down. He'd completed four of eight passes for 85 yards at the time of his injury.
"I've got a headache, I felt it right when I got hit and from there it hasn't gone away so they just kept me away from the game," said Calvillo after the game, adding that he didn't remember being hit but didn't think the impact with the ground was what caused his injury.
"I'm assuming that it is (a concussion)."
Calvillo was replaced by Josh Neiswander, who saw his first regular-season action at QB with the Alouettes after signing with them in 2011.
Saskatchewan wasn't immune to the injury bug either, as wide receiver Rob Bagg went down just before halftime after appearing to injure his left knee on a routine blocking assignment.
Bagg had season-ending surgery last year to repair a torn ACL in the same knee.
