Though his green monstrosity of car has been seen going to Mash Barn Lane regularly so would assume he has been training.I think all that has been reported (apart from rhetoric on NSC) is that he asked not to be included in the squad to sit on the bench. Never heard any viable report that he would refuse to resume his place between the sticks should Steele become unavailable for selection.
As for not jioining in with training, in the circumstances that is just as likely due to instructions from the club as anything else. Unhappy player wanting to leave? - don't come in and train with the squad. Pretty standard, I would think.
