MONTREAL -- Montreal Alouettes quarterback Anthony Calvillo will not play again this season after being out for more than two months with a concussion.
The 41-year-old Calvillo out of Utah State is the CFL's career passing leader and there is concern his 20-year career may be over.
General manager and coach Jim Popp said Calvillo recently had a setback. Popp said Calvillo can still exercise, but he's decided to "shut it down this season." His plans beyond this season aren't clear.
Calvillo was injured Aug. 17 when his head struck the turf following a hit in a game against Saskatchewan. He had headaches and vision trouble in the days afterward.
The Alouettes (6-9) are in third place in the East Division.
