Southampton have been kicked out of Saturday’s Championship playoff final — widely regarded as the richest game in world football — after being found guilty of spying on semi-final opponents Middlesbrough in one of the harshest punishments ever handed down in English football.

Tuesday’s decision by an Independent Disciplinary Commission appointed by the English Football League (EFL) dramatically changes the second-tier promotion race and gives Middlesbrough an unexpected lifeline after they lost 2-1 on aggregate to Southampton in the semi-finals.

Middlesbrough have now been reinstated and will face Hull City at Wembley on Saturday in a match often described as the richest in world football because of the huge financial rewards linked to promotion to the Premier League.

Even one season in the Premier League, followed by immediate relegation, is estimated to generate around £200 million ($268.10 million) over three seasons through broadcast revenue, sponsorship deals and parachute payments.

Southampton admitted to illegally spying on an opponent within 72 hours of a scheduled match and also confessed to filming training sessions involving Oxford United in December and Ipswich Town in April during the regular season.Southampton failed to win any of those matches.

The club had not issued a statement by midnight, though several reports indicated they planned to appeal the severity of the punishment. The EFL said Southampton have the right to appeal and added that “parties are working to try and resolve any appeal on Wednesday, 20 May.

”The EFL also stated that depending on the outcome of the appeal, Saturday’s fixture could still change, giving the south-coast club a slim chance of reinstatement.

Unprecedented ruling

The ruling could trigger a wave of legal complications, with some reports suggesting Southampton players may have grounds to sue the club for loss of earnings if they miss the opportunity to reach the Premier League. Other reports claim clubs that missed out on the playoffs could also seek compensation.

Southampton’s allocation of around 37,000 tickets for the Wembley final had sold out earlier on Tuesday.

While the club remained silent, Southampton fans reacted strongly online. Some defended the team, while others expressed embarrassment over the scandal.“Spying or not, we won fair and square on the pitch,”

supporter Melissa Earley Gordon told Southampton newspaper The Daily Echo.

However, Martin Sanders, who runs a Southampton fan channel on YouTube and had already booked tickets, travel and hotel accommodation, described the situation as “devastating.”

Southampton were relegated from the Premier League last season and struggled early in the current campaign before producing a remarkable turnaround, going unbeaten in 19 league games to finish fourth and qualify for the playoffs.

The south-coast club are the first to breach Football League Regulation 127, introduced after Leeds United were found guilty of spying on Derby County seven years ago — an offence that resulted in a £200,000 fine.
