Personally, I'd have put him on ice till the new year. Just rest and heal. Let the 3 guys we have now rotate at CB, at some time in the new year we will need him due to injury or major fatigue (perhaps both), then bring him in. But for now, just go with John, Ota and Kola.
It wasn't the timing of his comeback. Nor was it connect to any previous injury or weakness. It was total bad luck clashing with the goalie and falling badly. It's just such sad news. But I really believe he will return in Jan 17
