WINNIPEG, Manitoba — The Oakland Raiders and Green Bay Packers played their exhibition game in Canada Thursday on a shortened field out of concern for the safety of the field.

The game in Winnipeg was played on an 80-yard field with the goal lines starting at the 10-yard lines and no kickoffs. Teams received the ball at their 15-yard line, which is located at the normal 25-yard line.

The NFL said the field passed inspection on Wednesday, but both teams had concerns about the condition of the end zones, where the goal posts for CFL games are usually located.

That led to the decision to shorten the field.

Both teams held out almost all of their starters with the Packers announcing that 33 players weren't playing, including quarterback Aaron Rodgers. The Raiders had been planning to sit quarterback Derek Carr and most starters even before the problems with the field.

The Raiders decided to move one of their two home exhibition games to Winnipeg in a move that saved them $500,000 in rent at the Oakland Coliseum. The team is planning to move to Las Vegas in 2020.
