After noticing this pop up as an issue for me this season, and seeing others hinting at it, I thought I'd finally raise it. Before I started reffing, I'd never badly injured myself. A year and a bit into refereeing, and I've spent at least 3 to 4 months out injured in total. All but 1 of these injuries have come from refereeing on 4G (the one that didn't happened 3 days after a game on 4G, when I was still incredibly sore - that doesn't happen to me on grass!). Is this a common thing or is it just an unfortunate coincidence? I wear the same boots on Astro/4G as I do on grass (not sure if this is the norm? It was recommended to me when reffing at the Wolves academy when I spoke to their physio and a few of the coaches). If you experience this, how do you cope with it? Thanks!
