Wigan Warriors have been reprimanded and ordered to pay costs for postponing their Super League fixture against Widnes Vikings in February.
Because of Storm Doris and Wigan Athletic were playing the day after, Wigan decided, without consulting Widnes, the game should be called off.
The Cherry and Whites have to pay £2,000 in costs for the RFL.
An independent operational Rules Tribunal determined the Warriors breached operational rules and some of the league’s code of conduct.
The Rugby Football League has stated they will set up a working party so the stadium sharing clubs – Wigan, Hull FC, Salford Red Devils and Leeds Rhinos – can discuss the issues in relation to sharing a ground.
