Before I had seen the tackle, I said I thought it sounded like Arter's against Newcastle which I believed deserved a red card. Having now seen the Ralls incident, the tackles look different, but, essentially, the decision the refs have to make is very similar. Having looked at that link to what Mark Halsey said in the Sun about Saturday's sending off, which was posted in another thread, I think I might be wrong by a strict interpretation of the rules of the game - as the rules are worded, it seems hard to justify Mike Dean's decision although, morally, it was the right one as far as I'm concerned.
