Green Bay Packers linebacker has denied San Francisco 49ers coach Jim Harbaugh's claims that he is a dirty player following his hit on Colin Kaepernick.

Matthews said that he does not have to prove himself to anyone, but insisted that he plays the game to the best of his abilities.

"No, I don't have any reaction [to him]," Matthews told the Journal Sentinel. "I'm onto the next game.

"I'm an awesome player. I'm not a dirty player. I think my resume's pretty good right now. I think we're doing alright."

The Packers face the Washington Redskins on Sunday in their next game.
