If Darnell Dockett had suited up for Sunday's game between the Arizona Cardinals and the Oakland Raiders, he would have gotten a 15-yard penalty for taunting.

Instead the injured defensive end was on the sidelines, and he decided to use his down time to troll the fans in the stands behind him.

As it became clear that his Cardinals would beat the Raiders and drop Oakland to 0-6, Dockett scribbled a stinging message on a whiteboard and showed it to fans:



After the game, Dockett explained his actions on Twitter (note: he uses an expletive in his first tweet):



Dockett told ESPN that after he held up the sign, more objects were thrown his way by the notoriously rowdy Raiders fans.

Raiders fans join a long list of people and groups that Dockett has taunted, including Cincinnati Bengals backup quarterback A.J. McCarron, Chicago Bears quarterback Jay Cutler and PETA.

While Dockett was placed on injured reserve after tearing his ACL at practice in August, the Cardinals are off to one of their best starts in recent memory. After beating Oakland, Arizona is 5-1 and all alone in first place in the NFC West.

With the Jacksonville Jaguars' victory over the Cleveland Browns, the Raiders are now the only winless team in the NFL.
