I seem to remember, I'm sure Finny will confirm, either early Superleague / Heineken league we leant our backup NM to the opposition.
I wasn't as bad as Chris Newton, one Devils NM who left us and signed for Peterbough, standing aside to let a goal in, he literally leant on the pipes and gave us an empty netter, we were stuffing them by then so it didn't really matter apart from the fact he got gassed as a result.
