Nevertheless, Toronto still had a chance to pull out a victory. With 1:53 left in the game and Calgary deep in their own end, they punted on third down. Argo returner Harry Abofs, in an effort to capture the wet ball, accidentally kicked it out of bounds while reaching down. CFL rules state that when a ball is kicked out of bounds, possession goes to the opposing team, thus giving Calgary possession once again. Had Abofs knocked the ball out of bounds with his hand, Toronto would have had one last offensive series. Instead, Calgary ran out the clock and captured the 1971 Grey Cup.
