"The week's delay is the same for both sides so nothing has really changed from last week," added manager Darren Joy.
The Wanderers are forced into changes to the side that was scheduled to play against Corus last week. The experienced Harry Trelawny comes back in at scrum half following an injury to Tim Cronin and Greg Callow is also injured which allows Lewis Williams a chance to return to the squad following his involvement with the Blues last weekend.
The winner of this game will play Merthyr in the next round.
