O'Donnell v Muttley to replace Williams & Witter on Saturday

[scrap iron]

With Junior Witter and Danny Williams seeing their perspective opponents pulling out does anyone know if the John O'Donnell and Young Muttley British title-eliminator has replaced them as headliners? I think this is an excellent match-up, but is it a worthy of topping a bill that will be going live out on ITV4 or will the show simply get called off at the last minute?
