Just speculation is my guess, unless we've lined up a CB. Currently CG is one of our 4 CBs, and we can't make do with any less than four. Of course, the club can always bring one in out of the blue and surprise us (for instance, Duffy last year).
Considering how little Championship experience he's actually had, the PL would be a huge step up - for that reason a season long loan to a Championship club would make sense. Not unless we've got someone in before letting him go, though.
Thought he looked good in last week's friendly.
