Actually this is a very similar case with a couple of earlier players that got replaced. The players apparently just signed up, but didn't know what for. I'll try to find a replacement as soon as possible, if you wish to have an opponent instead of having a walkover. Also, I've noticed that you haven't been contactable very much either recently. If you feel that you're having too little spare time yourself, you can also give your place if you like, because I have an eager player in reserve(not myself) just in case.
