After much debate over artificial turf versus natural grass in the NFL, the union that represents the players recently presented data showing the notable difference in non-contact injuries between the two playing surfaces.
Data provided by the National Football League Players Association showed that during the 2022 NFL season, players suffered more non-direct contact injuries on turf than natural grass.
"Grass is a significantly safer surface than turf," JC Tretter, NFLPA president and author of the online post, said.
The association reviewed past data and found that 10 of the previous 11 years showed that the injury rate on synthetic versus natural surfaces was considerably higher. The NFLPA noted 2021 was likely an anomaly where the trend flat lined but increased again in 2022.
"Last year, the gap – much like the NFL's credibility with players on this issue – was as wide as it has ever been, proving that (as the NFLPA suspected) 2021 was, in fact, an outlier," Tretter wrote.

"Last year, the NFL touted data to push the narrative that turf was just as safe as grass," he continued on social media. "It highlights the credibility gap on health and safety and why players are right to call for safer surfaces."
In response to the NFLPA's claims, the NFL responded by saying there were no simple answers to the ongoing debate.
"The committee, including the NFLPA's experts, believe that simply playing on natural grass is not the answer to this complex challenge. Some artificial turf surfaces have a lower injury rate than some grass fields, and some grass fields have a lower injury rate than some artificial surfaces," Jeff Miller, the NFL's executive vice president of communications, public affairs and policy, said.
Miller went on to say that the league's goal is to decrease injuries on all surfaces.
"There are no simple answers, but we are committed to the substantial, ongoing work with the players and their expert advisers to make the game safer."
NFL players advocate for grass over turf
Tretter, a former NFL offensive lineman, isn't the only one vocal about how the artificial turf is significantly harder on the players' bodies than grass during the 2022 NFL season.

After the injuries on the artificial surface, Seattle head coach Pete Carroll commented about using manmade surfaces and what would be best for his players.
"I think we definitely need to look at this really seriously in the offseason again," Carroll said. "It's been a discussion before. We've got to do what's right, and we've got to do what's safest for the players, and we've got to make those choices. I would pound on the drum for that."
Following the 2022 NFL season, San Francisco 49ers tight end George Kittle urged sports fans to sign a petition by Pennington Grass Seed to "Flip the Turf."
"Of the 32 teams in the NFL, 16 teams still play on artificial turf, despite the undeniable risk it poses to both players and the environment," the petition stated.
"I’ve been saying, artificial turf feels like playing on cement. It’s time to play smarter, not harder," Kittle wrote on Twitter.
Just before Thursday's 2023 NFL Draft, the petition had nearly 30,000 signatures.

There is no set rule for whether a stadium uses real grass or turf, and the decision is up to local management.
For some stadiums in the West, like Levi Stadium in San Francisco and State Farm Stadium in Arizona, teams have the ability to bring in new grass throughout the NFL season that is grown at a nearby farm.
