Aston Villa chief executive Keith Wyness has slammed the FA after being hit with a ban from football.
Wyness,59, has been fined £10,000 and given a three-week suspension over his social media use.
He shared a Twitter video of Villa being denied a penalty in their final Championship game with a caption questioning if under-performing referees had “disabilities”.
He stormed: “My record in football has been spotless until this event.
“I am both surprised and disappointed at the severity of the punishment. I will go to my grave knowing it was an honest mistake.”
Wyness swiftly deleted the Tweet and apologised once a supporter pointed out his actions but the FA still acted.
He added: “I have received the findings of a recent disciplinary hearing into a re-tweet that I mistakenly sent on the last day of the season.
“I requested a personal hearing earlier this week because it was hugely important to me to firstly apologise for my genuine mistake in person and I also wanted the opportunity to make it clear to the panel I am really remorseful and extremely disappointed in myself for making such a silly mistake.
“When my error was first brought to my attention by a supporter, I immediately deleted the retweet and issued a public apology.
“I simply saw the video and not the comment attached to it. I send my sincerest apologies to anyone I may have offended and would like to re-affirm the club’s commitment to its work with people of all ages and abilities.”
