Colin Kaepernick’s season seems to be getting longer by the minute.

TV cameras on the Fox broadcast during Sunday’s game in San Francisco picked up sound of Green Bay linebacker Clay Matthews shouting at Kaepernick: “You ain’t Russell Wilson, bro.”

Matthews’ comment came in the fourth quarter of the Packers’ 17-3 win.

Perhaps symbolizing the 49ers’ offensive ineptitude, Matthews produced a third-down sack of Kaepernick in the third quarter and celebrated by “Kaepernicking,” with Matthews kissing his own right biceps.

Matthews said it was not planned and all in fun.
