The NFL has installed a hybrid field for its two games in Frankfurt next month.
The hybrid surface was installed last weekend at Deutsche Bank Park ahead of the Nov. 5 game between the Kansas City Chiefs and Miami Dolphins.
The New England Patriots will then play the Indianapolis Colts at the same stadium a week later.
After the NFL's first-ever regular-season game in Germany last year, players and coaches from the Tampa Bay Buccaneers and Seattle Seahawks complained about the surface at Allianz Arena in Munich.
