Leigh Leopards and Wigan Warriors, two professional rugby league teams in England, are under investigation by the Rugby Football League (RFL) into their conduct over the past year. The probe follows tensions that arose during a Super League play-off match between the two clubs last October. The game, which Wigan won 18-6, was marred by a dispute over how many tickets each team should be allocated for the event. Leopards owner Derek Beaumont had suggested his team might not participate if the allocation of 4,800 tickets was not adjusted. Wigan Warriors have since moved on to the next stage of the competition, set to host Wakefield in the play-off semi-final this Saturday. Earlier this week, Wigan stated that any team they faced in the semi-final would be allocated 5,000 tickets. This comes after Trinity defeated Leigh in an earlier eliminator match, which meant that Wigan would not face the Leopards in the semi-finals. The RFL has informed both clubs that an independent investigation will be conducted into their behavior and actions, as well as the decisions made by the governing body over the past 12 months. This investigation will look into all relevant matters related to the clubs and the RFL. The RFL and RL Commercial have said they will not provide further statements until the investigation is completed. BBC Sport has reached out to both Leigh Leopards and Wigan Warriors for their comments on the situation, but neither club has responded yet. The outcome of the investigation could have implications for how future events are organized and how disputes between clubs are managed in the Super League.
