MONTREAL - Anthony Calvillo is back with the Montreal Alouettes.

The CFL club named Calvillo, pro football's all-time passing leader, as an offensive coach.

Alouettes head coach Tom Higgins said Calvillo's duties will be clarified once an offensive co-ordinator is hired.

The appointment is hardly surprising, as the 42-year-old had said when he retired following the 2013 season he wanted to get into coaching after taking a break from the game.

Calvillo played 20 seasons in the CFL, the last 16 with Montreal, and led the Alouettes to eight Grey Cup appearances, winning three.

The three-time league MVP retired with 79,816 career passing yards and is the Grey Cup's most prolific passer with 2,470 all-time yards.
