SANTA CLARA, Calif. -- Clay Matthews pulled out one of San Francisco 49ers quarterback Colin Kaepernick's celebratory moves Sunday.
After the Green Bay Packers linebacker sacked Kaepernick in the third quarter, Matthews flexed his right arm and kissed his bicep.
It's a gesture Kaepernick often makes after he scores a touchdown.
For Matthews, it was his third sack of the season. He went the first two games without a sack but had two Monday night against the Kansas City Chiefs.
Matthews' usual celebration is the double biceps flex.
