I believe that Madley got injured in the fitness test and therefore as the fitness test wasn’t passed he is no longer eligible for promotion.
I have to say that sounds extremely harsh that a referee can perform well for a whole season and then an injury or medical incident would stop them from being promoted. Surely if it’s an injury a referee should be given another opportunity to pass that? Is that the normal procedure? I thought officials had a number of opportunities to pass a test especially if injury was the reason for not passing first time?
