I may be wrong, but watching the game yesterday, it looked like Nelson was playing on the left, when in the previous game, he was on the right. My immediate thought is that this was a 'try-out', to see how he got on, playing on the left. If it worked, then when Morrison was fit, he (Morrison) would step back in on the right, Nelson stays left, and Flint would find himself on the bench. So did it work? Hmm, hard to say. Nelson didn't look that comfortable on his 'wrong' side, so it might be we have to wait for both Morrison and Bamba to return, before we get a more reliable (if error-prone) defence.
