The 49ers were part of the US consortium who took control of Rangers last year but York is not involved in the day-to-day running of the club.
Rangers and Leeds have both said they will not be commenting.
The 49ers said: “As this is a legal matter, which has been resolved, we will not be providing any further comment at this time.”
York became a co-owner of Rangers through 49ers Enterprises, the investment arm linked to the NFL’s San Francisco 49ers, where he serves as chief executive and principal owner.
In May 2025, a consortium led by US businessman Andrew Cavenagh and 49ers Enterprises completed a takeover of Rangers after acquiring a controlling 51% stake in the Scottish Premiership club.
Cavenagh became Rangers chairman, with 49ers Enterprises taking a leading role in the club’s ownership.
The takeover followed months of negotiations and brought Rangers under majority American-backed ownership.
49ers Enterprises first invested in Leeds United in 2018 when the club was in the Championship, steadily increasing its investment as the Whites returned to the Premier League following a 16-year absence, before assuming full control in 2023.
As an NFL owner, York is subject to league policies. “We are aware of the matter which will be reviewed under the personal conduct policy,” the NFL said.
