Thank you ref. IMO it will be down to his wording in his match report. Looking at the situation, he got the call right. However, the club website is citing "for what was deemed to be denying an obvious goalscoring opportunity."
If there was no mention of failure to attempt to play the ball then the rescinding is a no brainer. I think that is what's happened. Fozzy was in a position where he might have been able to intervene and the FA appear to have accepted that.
