Yiadom and Marsh-Brown selected for upcoming England C internationals.
No Barnet players have been named in Roy Hodgson's squad for Brazil but two Bees will be representing the Three Lions this summer.
Andy Yiadom is one of four new faces in Paul Fairclough’s latest England C squad ahead of the International Challenge Trophy Group A match with Slovakia in Poprad.
Keanu Marsh-Brown has retained his place in the squad but there is no place for Jake Hyde who was included during the season.
The Three Lions travel to Slovakia for the tie which will take place on Saturday 24th May before making their way to Hungary for a friendly at the Szusza Ferenc Stadium in Budapest four days later.
Yiadom joins FC Halifax Town’s Marc Robers and Gateshead pair Marcus Maddison and James Marwood as players who could make their England C debut.
