The WSL has launched an investigation into Crystal Palace making substitutes on four separate occasions in their win over Everton. Palace earned the 1-0 triumph at home to the Toffees but run the risk of the match being replayed, or even having points taken away from them as a result. Lexi Lloyd-Smith’s 34th-minute goal sealed the win for Palace, but this isn’t the end of the matterGettyEagles boss Jo Potter made four substitutions during the game, with Abbie Larkin, Ashleigh Weerden, Allyson Swaby and Kirsty Howat all coming on. While managers are permitted to make up to five substitutions during matches, they must be done within three windows. The introductions of Larkin, Weerden, Swaby and Howat all happened on separate occasions, in the 62nd, 83rd, 90th, and seventh minute of stoppage-time respectively. It’s reported that the officials of the Crystal Palace vs Everton clash will not be assigned games during next weekend’s WSL and WSL 2 fixtures.
