I don't remember seeing any report of Healey going out on loan again - although earlier in the summer Warnock said he would like that to happen. He needs to play every week not warm a bench or play u23 matches.
O'Keefe has only just got back on the grass after a long-term injury.
If there is going to be a reprieve (and a place in the 25 man squad) for one of Tomlin, Pilkington, O'Keefe or Healey I hope it is Pilks.
Edit - Scratch that - just done a recount. With Arter signing there won't be any spare places in the 25 - so all of them will have to move on.
