Pete Carroll and Seattle Seahawks safety Quandre Diggs would like to see a close reexamination of whether NFL stadiums should exclusively use natural grass.

The ongoing conversation about the safety of playing on artificial turf versus natural grass has been brought back up after DK Metcalf and J.C. Jackson suffered knee injuries during Sunday's game at SoFi Stadium, both on noncontact plays.

L.A.'s SoFi Stadium, home of the Chargers and the Rams, uses an artificial surface.

"I think we definitely need to look at this really seriously in the offseason again," Carroll said when asked about the grass-turf debate. "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."

Fourteen of the NFL's 30 stadiums use an artificial surface, including the Seahawks' Lumen Field. 

"So you see that and you just kind of wonder why can't we have natural grass everywhere," Diggs said. "I love playing in San Francisco and things like that where it's grass and you just go out there and you just go play. Hopefully, we're doing some research on it and seeing what we can do to make things better."
