Shaun Derry has admitted he was in 'shock' after being sent off in Queens Park Rangers' recent 2-0 defeat to leaders Manchester United.
The veteran midfielder was issued a straight red card 14 minutes into the Old Trafford contest earlier this month after Ashley Young went down in the penalty area.
Contact between the two was minimal and the 34-year-old was convinced something else must have transpired during the incident for Lee Mason to issue the red.
Even Derry himself was unsure what he has had done, believing he must have kicked out for Young to end up on the floor - circumstances that left him 'baffled'.
"I was baffled by Young being on the floor because the amount of pressure we put on each other was so minimal. To see somebody on the floor was... well... a shock to me," he said in The Independent.
"I thought something else must have happened - without me knowing. So I was thinking: 'Have I kicked him?' That is why I reacted how I did - just going gently off the pitch and down the tunnel. I didn't realise what I'd done.
"So I wanted to take my time when I'd been sent off. Sample an atmosphere of some kind, because ultimately there's not going to be a lot of occasions where I'm going to play at Old Trafford ever again. It might not ever happen again.
"I wanted some sort of memory of the situation, of me being a player at Old Trafford, being captain. It was a bad one, maybe, but I didn't want the whole thing to be dazed... a blur in my mind."
But when Derry watched the incident again on the TV monitor in the tunnel he realised what he had transpired.
The veteran midfielder does not feel Young tried to cheat, only that he was trying to win 'an advantage' for the Red Devils.
"That's when you're thinking: 'Hang on a minute. I've just led a Premier League side out at Old Trafford. My parents to see me being captain. All that's gone'," he continued.
"Take away the promotions and the good games and individually that day was the highlight of my career.
"I never felt Ashley Young tried to cheat me. Just to gain an advantage for his side as he did again [the next week] against Aston Villa."
