Neal Maupay was left out of the Everton squad to take on Leeds United on Tuesday after failing to be registered as a Blues player despite being at the club for four days now.
With Monday being a bank holiday, the Premier League used Friday noon as the cut off point for new players to be registered for Tuesday's matches.
The Everton new boy was registered by the club on Friday afternoon, but the weekend and bank holidays are not deemed as working days for the Premier League so the striker misses out at Elland Road.
