Former NFL and CFL offensive lineman Edwin Harrison joins the Roughriders as the offensive line coach after spending the last two seasons with the Toronto Argonauts.

The 39-year-old served as the Argos’ running backs coach and run game coordinator. Under Harrison’s tutelage in 2023, the Argos’ running backs powered the team to 2,046 yards on the ground, with 1,000-yard rusher A.J. Ouellette leading the way. Ouellette was twice named PFF’s Running Back of the Month (June and August) and he was the Running Back of the Week five times throughout the season (weeks 2, 3, 8, 9 and 12) en route to becoming an East Division All-Star.

Prior to joining the Argonauts’ coaching staff, Harrison was teaching geography while serving as the assistant head coach and offensive line coach at Marshall High School in a suburb of Houston, Texas. He is a two-time Grey Cup Champion, with the Stampeders (as a player in 2014) and Argonauts (as a coach in 2022).

He was an offensive lineman with the Stampeders from 2010 to 2015. For much of that time, he was a teammate of defensive lineman Corey Mace. Mace was named the Roughriders’ Head Coach on Nov. 30.
