It was reported that he had signed and gone on loan to Burgess Hill but wasnt eligible for registration or to play which is not the same as signing for them, He became a Crawley employee and player.
It could well be that by signing until Christmas it given them the chance to look at him before either letting him go or extend his contract whilst giving him the chance to see what they have to offer so a win all round for all concerned.
Just read the last para so obviously he was released...
