Calvillo, who played 16 of his 20 seasons with the Montreal Alouettes, leaves the game as pro football’s career passing leader with 79,816 yards, having broken the record of fellow ex-CFL pivot Damon Allen.

He also set all-time CFL records for completions (5,892) and touchdowns (455). The completion mark is second only to former Green Bay Packers quarterback Brett Favre, while only Favre and current Denver Broncos signal-caller Peyton Manning have thrown for more TDs.

Calvillo competed in eight Grey Cups, winning in 2002, 2009 and 2010. After the 2010 victory, Calvillo revealed he was facing a cancer scare and had a complete thyroidectomy after the season before returning the following campaign.

He was also named CFL outstanding player in 2003, 2008 and 2009.

Calvillo flourished during his time in Montreal after a slow start to his career in Las Vegas and Hamilton.

Known for his game preparation, Calvillo studied the game thoroughly while possessing a quick release and ability to read defences.
