Claire Kittle, wife of San Francisco 49ers tight end George Kittle, is pushing for two NFL rule changes that would mandate natural grass playing surfaces across all stadiums amid concerns about player injuries.
The advocacy for "grass everywhere" was reported on October 31, 2026. George Kittle, who wears number 85 for the 49ers, appeared with his wife at the 2023 Pro Bowl Games at Allegiant Stadium in Paradise, Nevada.
