Ndamukong Suh has said that he does not believe reports that one of his teammates criticised him anonymously in the media.
Yahoo! Sports quoted one of Suh's Detroit Lions colleagues as saying that the defensive tackle loses his cool and causes controversy.
Suh told the Detroit Free Press: "I don't care. You know where my locker is if you got something to say to me.
"But I really, honestly, in my heart of hearts, I really don't think it's true. And it's unfortunate that things are written like that. I mean, if it is true, it is true. If it's not, it's not."
Suh recently came in for criticism when he kicked Houston Texans quarterback Matt Schaub in the groin, resulting in a $30,000 (£18,600) fine.
