Newcastle Falcons have been forced to postpone Friday night's Aviva Premiership clash with Bath at Kingston Park.
With more heavy snow forecast in the north-east it was felt an early postponement was the best option to prevent those due to attend the game making an unnecessary journey.
But the weekend's other fixtures are currently expected to go ahead.
A Premiership Rugby statement read: "Premiership Rugby has invested significantly in pitch protection, but with more snow overnight in Newcastle, in addition to concerns about the pitch there is now significant concern about the safety of the spectator areas.
"With an additional five centimetres of snow forecast for Newcastle this evening, an early postponement was considered the best option to avoid unnecessary travelling for supporters, players, officials and the media.
"Having looked at the weather forecast and with pitch protection systems in place at the other grounds, further postponements (for matches at Headingley Carnegie, Edgeley Park, the Madejski Stadium, Vicarage Road and Adams Park) are not anticipated."
Despite that confidence Sale have appealed for supporters to help them clear the Edgeley Park playing surface and perimeter of snow ahead of their Friday night clash with Gloucester.
