Crystal Palace have been demoted from the Europa League to the Conference League next season, Uefa have ruled.
The governing body's decision stems from Palace breaching its multi-club ownership rules and Uefa said the Eagles could appeal its ruling with the Court of Arbitration for Sport.
Nottingham Forest, who finished seventh in the Premier League last season, could replace FA Cup winners Palace in the Europa League.
Eagle Football Holdings - owned by American businessman John Textor - holds stakes in Palace and Lyon, with Uefa rules stating that clubs owned, to a certain threshold of influence, by the same person or entity cannot compete in the same European competition.
Uefa's rules set a deadline of 1 March 2025 to show proof of multi-club ownership restructuring - a deadline which Palace missed.
Palace argued Textor does not hold any decisive influence at the club, but Uefa have not accepted the Premier League side's defence.
Lyon, who also qualified for next season's Europa League, take precedence over Palace because of their higher league position.
The seven-time French champions finished sixth in Ligue 1, with Palace 12th in the Premier League but qualifying for European competition by winning the FA Cup.
Earlier this week Lyon won their appeal against relegation from Ligue 1 after they were demoted for financial reasons, which affected Palace's chances of playing in the Europa League.
Had Lyon's relegation been upheld, they had agreed with Uefa to be excluded from the Europa League, clearing the way for Palace to play in the competition.
English football has two allocated Europa League spots, with Aston Villa securing the other after finishing sixth in the Premier League.
Forest replace Palace in the Europa League after finishing seventh, with their Conference League spot going to the Eagles instead.
