Hi, this is not something that I recall seeing before. Are you able to let me know the injury that the player was suffering from? It may not be something you saw before seeing the deal 'cancelled' but any information would help in our attempts to track down why this happened.
We will take a look in to this and I will let you know if we have any news about it. If you could let us know if you see it again, it would be useful to know the player's injury and time remaining unavailable at the time that you are attempting to sign him.
