GREEN BAY, Wis. -- It's hard for the Packers' Clay Matthews to let things go on the field. Give the Pro Bowl linebacker a clear path to a quarterback or running back and he'll usually lock on for a takedown.

But as far as that 49ers game last week and coach Jim Harbaugh's criticism? Yeah, Matthews is moving on.

In his first meeting with reporters since Sunday's 34-28 loss in San Francisco, Matthews sidestepped a question on whether he'd received notice from the NFL about a potential fine following a late hit on quarterback Colin Kaepernick that preceded a sideline scrum with offensive lineman Joe Staley.

"Um, I'm not really going to discuss all that right now, but on to the next game," Matthews said at his locker after practice Thursday. The Redskins visit Lambeau Field in the Packers home opener Sunday.

Matthews didn't bite after being asked about Harbaugh's remarks earlier this week.

"If you're going to go to the face, come with some knuckles, not an open slap," Harbaugh said then. "I think if that young man works very hard on being a tough guy, he'll have some repairing to do to his image after the slap."

Anything, Clay?

"Nah, I don't have any reaction. I'm on to the next game," he said. "I'm not worried about it."

Matthews was asked if he considered himself a "dirty player."

"Next game!" he exclaimed with a smile, drawing laughs. "I'm an awesome player, not a dirty player."

The Packers did limit San Francisco on the ground. Kaepernick and Frank Gore were held in check on the ground, for the most part. Kaepernick beat the Packers with his arm this time, throwing for 412 yards and three touchdowns.

When asked, Matthews could remember only one time in his career when he was fined, for a face mask on Bears quarterback Jay Cutler in 2010.

Otherwise, the resume is clean -- look it up, he told reporters.
