The FA Cup winners have been demoted to the Europa Conference League due to shareholder John Textor also owning fellow qualifiers Lyon. Lyon earn their place ahead of Palace because finished higher on the Ligue 1 table.
Palace have announced they're taking the matter to the Court of Arbitration in Sport, with Textor having now sold his stake to Woody Johnson, though not before a deadline set by UEFA.
Meanwhile, Palace fans from the Holmesdale Fanatics have presented the UEFA front desk at Nyon with a suitcase stuffed full of fake cash.
A letter addressed to UEFA president Aleksander Ceferin was included in the presentation, urging for the decision to be reversed.
The supporters also traveled to Lausanne, where the Court of Arbitration in Sport is held, and held up a protest banner.
