Recently while watching (not reffing) a game at step 5 in the English non-league system there was an incident in the game where the ref did not show up presumably for a valid reason. To make up for this a linesman acted as the ref and the teams supplied a 'linesman' for each half. I was a little confused as I know linesman don't necessarily need to have all the 'kit' in lower leagues, grassroots etc. And just wandered what the rules were surrounding this. Cheers for any help!
