Wycombe's Tommy Doherty was sent off last night in their game against Wrexham and is therefore expected to miss Saturday's game at Edgar Street.
Update: The FA have confirmed that Doherty will serve a one match ban and miss Saturday's game.
Meanwhile Wycombe manager Paul Lambert is asking his supporters to travel to Hereford for the game.
"Our fans have been wonderful on the road this season, they have travelled in good numbers and made a tremendous amount of noise. This is a big game so it would be great if a few more people could make the trip and keep up the noise," Lambert told the Wycombe website.
