During the breaks in the Packers-Raiders preseason game, I tried to research what went on that caused Coach Matt LaFleur to withhold his top 33 players from playing on the field of the Winnipeg Blue Bombers.
It appears that when the goal posts, which are located differently on Canadian Football League fields, were moved, the holes left were filled poorly, creating some footing concerns. Never mind that the game was played on an 80-yard field, the thing that apparently caused LaFleur to sideline all his starters, and eleven others, was concern over these two spots of turf.
I saw a photo that showed the supposed culprit: about a 20” by 20”square; I assume there were two of these, one near each end zone.
