Danish club Viborg will be without two players for Thursday's Europa Conference League match against West Ham after post-Brexit rules meant they were unable to secure visas to come to London.
Nigerian winger Ibrahim Said and Gambian forward Alassana Jatta will not feature at the London Stadium due to entry rules for non-European Union citizens.
Said, 20, has started the majority of Viborg's matches so far this season and would have likely started for the Superligaen club on Thursday night.
Jatta, 23, has made only two substitute appearances so far this campaign but did come off the bench in their third qualifying round, second leg game against B36 Torshavn and scored in a 2-1 win.
