I think that makes Flores and both keepers on just 1 year deals. There may be others I've forgotten.
Wouldn't be surprised if the deal was sorted very quickly and therefore Flores' personal terms remain the same as they were on his Hull deal, hence it only being for 1 year. Of course, that all depends on whether he had just the 1 year remaining on his deal with Hull.
Sid Nelson and Ali Koiki also I believe are on 1 year deals
