Members of the organization do not accept the field conditions where they have to prepare for games against the Chiefs
Sources told ESPN’s Adam Schefter that field conditions at the San Francisco 49ers’ practice facility at UNLV have drawn widespread disapproval from many members of their organization.
The NFL laid a grass field over artificial turf and began installing it just last week, when the NFL typically requires Super Bowl practice fields to meet certain standards in December, sources told Schefter.
The hardness rating for NFL fields averages 78, and no fields are lower than 70. Sources told Schefter the 49ers’ field is believed to be in the 50 range.
The 49ers will hold their first on-field practice this Monday.
The Kansas City Chiefs will practice at the Las Vegas Raiders training facility this week.
The league inspects playing surfaces with the NFL Players Association (NFLPA) before each Super Bowl and approved the use of each facility this week.
The playing surface in Glendale, Arizona, was one of the biggest stories for last year’s Super Bowl, particularly the slippery grass that caused Chiefs and Philadelphia Eagles players to have trouble keeping their balance throughout the game.
CBS Sports was the first to report the 49ers’ dissatisfaction with their training camp.
