I was surprised when he went back on but he had just walked 1/4 way round the pitch which I'm sure would constitute part of the assessment.
It was good that the ref stopped play to come and check and you would like to think that the club staff were sure that he was ok to continue at that time. The fact he lasted 30 seconds shows otherwise and perhaps just goes to demonstrate that whatever the tests are, when you are time critical (to get a player back on the pitch) then you are not allowed to take the time to assess fully - some symptoms don't show immediately or even a few minutes after the incident.
When his legs went was distressing to watch.
The main thing is he came and off and if last nights reports are correct then he is doing well.
