TBF Robins thought Hamer was out for two games as well when he got his fifth yellow. I wouldn’t put it past him to be wrong about this.
As I mentioned in the Eccles thread there was a couple of 'if possibles' in the interview. So, it did cross my mind that we may not be aware of the ruling.
However, I have to say it would be a bit ridiculous on Robins' behalf (and AV, Badlan as well) if he brought Eccles back on the basis of loaning him out again but didn't think to enquire whether it was possible first.
