Calvillo, 42, announced his retirement in January following an illustrious 20-year career. His last CFL game happened to be against the Riders, in Regina, and the Montreal Alouettes are set to retire No. 13 — Calvillo's jersey number — Monday when the Alouettes host Saskatchewan.
Using the game against against Saskatchewan for the ceremony also ties in to the Roughriders' oft-referenced "13th man" — a nod to the value of the support of football fans.
Calvillo's ties to Saskatchewan, however, are more substantial than a numerical coincidence.
He has been a guest coach for the University of Saskatchewan football team the Huskies. He is also good friends with the Rider's quarterback, Darian Durant.
Calvillo is set to talk to CBC Radio host Sheila Coles, on The Morning Edition Friday at 6:45 a.m. CST.
Among the likely questions, Calvillo may be asked to comment on the return to the game, at age 41, of Kerry Joseph, who is joining the Roughriders because of an injury to Durant.
You can listen to the interview, live at 6:45 a.m. CST using the CBC Radio app or by going to the CBC Saskatchewan homepage and clicking on the Listen Live box, in the upper right hand corner of the front page. The Morning Edition will also have updates on their show homepage.
