Houston Dynamo midfielder Colin Clark apologized Saturday for hurling a gay slur at a ball boy during Friday night's game against the Seattle Sounders FC at CenturyLink Field, ESPN reported.

When 27-year-old Clark, who is in his third season for the Dynamo, is forced to pick up a ball knocked out of bounds, he utters a gay slur toward the ball boy.

Clark apologized in three messages posted on Twitter.

“I'd like to offer a sincere apology to everyone who watched the game, especially the ball boy for whom I used awful language toward.”

“I didn't mean to disrespect anyone and am sorry for letting my emotions get the best of me,” Clark messaged to his 560 followers. “It's not who I am and it won't happen again.”

He also messaged @gay4soccer, the user who posted video of Clark's outburst on YouTube. (The video is embedded in the right page of this page. Visit our video library for more videos.)

“@gay4soccer I'm very sorry for my actions tonight and I would love for you to consider me a #soccerally moving forward.”
