Overview
- The Patriots began removing the artificial turf and reinstalling the pre–World Cup surface after reports on Sunday said an independent NFL/NFLPA lab deemed the first post–World Cup turf noncompliant.
- Patriots COO Jim Nolan said the team is installing the same turf version used before the World Cup so players will see a surface similar to last season.
- The recent turf had met FIFA Pro and routine NFL performance checks but failed league lab rules because Gillette uses a stone‑dust sub‑base and the field did not include the elastic 'E‑layer' that the lab requires in standard installs.
- Kraft Sports Group asked for an out‑of‑window retest but was told league testing cannot be done until the next procedural window in early 2027, so the team must complete the changeover and hope the replacement clears certification before Thursday's preseason opener.
- The episode highlights a larger turf‑versus‑grass conflict exposed by temporary World Cup grass, since permanent grass needs costly sub‑base work and testing rules that will likely surface in future NFL/NFLPA bargaining and stadium planning.
