SANTA CLARA — Jim Harbaugh offered a parting shot at Packers linebacker Clay Matthews: Slapping is not the tough-guy way.
Harbaugh said Monday that Matthews threw one punch and slapped 49ers left tackle Joe Staley when they tussled following Matthews' late hit on quarterback Colin Kaepernick in the second quarter of San Francisco's 34-28 season-opening win against Green Bay on Sunday.
"If you're going to go to the face, come with some knuckles, not an open slap," Harbaugh said. "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."
Matthews promised leading up to the game that Green Bay would target Kaepernick after he ran for a quarterback-record 181 yards to beat the Packers in the playoffs eight months ago, and Matthews did just that. On the play, he threw his right arm around the lower part of Kaepernick's neck.
"Like I said last week, usually a man will tell you his bad intentions if you just listen. That certainly was a cheap shot, launching, clotheslining to the neck-head area," Harbaugh said. "Bad play."
