Reveling in the Oakland Raiders' 24-13 win over their Bay Area rivals, the San Francisco 49ers, linebacker Sio Moore decided to twist the knife just a little bit.

Moore posted a photo of himself and Colin Kaepernick going face to face. He captioned the picture, "There's a difference between boys and Men... Freakin chump":

Prior to the altercation, the two had an exchange in the tunnel at halftime. TMZ Sports provides video of the incident:

Moore had a tackle for loss in the victory.

It was the first time Oakland had beaten San Francisco since 2000, so you can understand why the 24-year-old decided to make the most of the Raiders' current bragging rights.
