Reading defender Matt Mills has issued an apology to the club's fans after making a rude gesture towards a section of supporters.
Mills signalled to the crowd during the closing stages of Reading's 1-0 win against Queens Park Rangers at the Madejski Stadium on Tuesday.
The 23-year-old has been disciplined internally by the club, after getting angry at the crowd's reaction to a poor pass.
"There are no excuses for what I did and I'm sorry for my reaction," he told the club's official website.
"I was out of order, but nothing like that has ever happened to me before and I was wrong. I've been around the game long enough to know that shouldn't happen.
"I feel like I've let a lot of people down - Brian (manager, McDermott) especially. He was the person who put me in the team and gave me a run of games.
"He's the one who gave me the captain's armband, which was a massive goal of mine when I joined Reading. Now the only way I can repay him is to keep performing for him.
"It's a massive honour to represent Reading and to react how I did doesn't put myself nor the club in a good light. So I just want to apologise to the fans, the club and everybody here."
Manager Brian McDermott added: "We have taken disciplinary measures and Matt is fully accepting of mine and the club's position. Now we can move forward."
Reading have dragged themselves out of the relegation mire of late and are even harbouring hopes of finishing in the play-offs this term.
Their next game in the Championship is a trip to the Riverside Stadium at the weekend to play Middlesbrough.
