NFL mandates playing surfaces for all stadiums meet new standards by 2028 to enhance player safety

The playing surfaces at every NFL stadium will have to meet new enhanced standards set through lab and field testing by the start of the 2028 season.

NFL field director Nick Pappas detailed the plans for a program on Thursday that will provide each team “a library of approved and accredited NFL fields” before the start of next season. Any new field will immediately have to meet those standards and all teams will have two years to achieve the standards, whether they use a grass or synthetic surface or a hybrid.

Most artificial surfaces are replaced every two or three years, Pappas said. Natural fields can be replaced several times a season.

Pappas said the fields will have undergone extensive testing and been approved by a joint committee with the NFLPA.

“It’s sort of a red, yellow, green effect, where we’re obviously trying to phase out fields that we have determined to be less ideal than newer fields coming into the industry,” he said. “This is a big step for us. This is something that I think has been a great outcome from the Joint Surfaces Committee of the work, the deployment and development of devices determining the appropriate metrics, and ultimately providing us with a way to substantiate the quality of fields more so than we ever have in the past.”

Pappas said fields have been tested in labs and on site using two main tools. One is called the BEAST, which is a traction testing device that replicates the movements of an NFL player. The other is called the STRIKE Impact Tester, which helps determine the firmness of each field.

The goal of the league is to find fields that are as consistent as possible across all 30 NFL stadiums, as well as at each stadium throughout the season. Pappas said the “key pillars” for a field are optimized playability, reducing injury risk and player feedback.
