He’s got more passing yards than Brett Favre, Fran Tarkenton and even Dan Marino, but most football fans have probably never heard of Damon Allen.

The forty-three year-old Allen, a 22-year veteran of the Canadian Football League, recently passed former CFL QB and 2006 NFL Hall of Fame inductee Warren Moon as pro football’s all-time passing yardage leader. Allen passed Moon’s previous record of 70,553 yards while leading his Toronto Argonauts to victory over the Hamilton Tiger-Cats. The game was stopped while in progress for a presentation by CFL Commissioner Tom Wright.

“Over the last 22 years, I’ve had the honor and the pleasure of playing in front of great fans across the CFL,” Allen told the CBC. “I’m just looking forward to going back to Toronto and celebrating next week.”

Damon, NFL Hall of Famer Marcus Allen’s younger brother, has played in the CFL since 1985 with seven teams. He was MVP of the CFL’s Grey Cup championship game in 1993 and 2004 and Most Outstanding Player of the league’s regular season in 2005. In his remarkable career, he has thrown for over 4,000 yards in five different seasons and even topped 5,000 passing yards last season for the Argonauts. Allen now has an amazing 70,596 career passing yards.

Moon was the featured guest honoring the all-time passing leader at last Saturday’s “Damon Allen Day” in Toronto.

“The main reason I’m here today is not because he broke my record, but because of the respect I have for Damon Allen as a person,” Moon said. “You guys have really been blessed to have an athlete of his caliber in your city.”
