Oakland Raiders Linebacker Sio Moore Calls 49ers QB Colin Kaepernick a "Chump" After Halftime Altercation

The Oakland Raiders hadn't beaten the San Francisco 49ers since 2000 before their 24-13 victory on Sunday, so its safe to say there has been a lot of built up tension brewing between the two rivals. That tension was apparently released Sunday, when Raiders linebacker, Sio Moore, called out 49ers star quarterback, Colin Kaepernick, jawing at the quarterback during halftime and posting a picture of the altercation on his Instagram account after the game.

"There's a difference between boys and Men ... Freakin' chump," Moore wrote in the caption of the photo, which was filtered into a comic-book style rendering of the heated moment.

Obviously, it is Moore here who believes he is part of the "Men," category, with Kaepernick regulated to the role of "boy."

What's the old phrase? "Act like you've been there before"?

TMZ caught footage of the altercation between the two players. On the video, Kaepernick says to Moore, "I'm coming for you," and nods his head.

ESPN reports this came after Kaepernick shoved a cameraman out of the way in frustration.

Moore finished with one tackle for a loss in the game.

Kaepernick played poorly, being intercepted twice and sacked five times. After the game, he was asked if the bad blood between the two California teams got to his head.

"I don't worry about things like that," Kaepernick said to ESPN.
