Am I right in thinking that a player can only be signed on a short term loan deal for an accumulative period of three months in a season? If so Ridehalgh would need to be signed on a season long loan deal and Huddersfield wouldn't be able to recall him so this might be a stumbling block.
Unless my understanding of the rules are wrong, of course...
You are indeed correct, I have a feeling he will be back in January
