Team and league officials were concerned about the condition of the turf at Investors Group Field - home to the CFL's Winnipeg Blue Bombers - after a goal-post relocation in one of the end zones. CFL goal posts are positioned at the front of the end zone, while NFL goal posts are placed at the back.
Referees and officials from both teams then elected to shorten the field. The area from the 10-yard line to the goal line served as end zones on both sides of the stadium. The reconfigured end zones kept the affected turf out of bounds on the one side of the field.
The Packers and Raiders also skipped kickoffs as a result of the shortened field, instead taking possession on the 15-yard line.
In a statement obtained by Josh Moser of FOX 11, the NFL said the turf "met the mandatory practices for the maintenance of surfaces for NFL games" when inspected a day before the contest.
