Darnell Dockett Taunts Raiders Fans With Handwritten Sign, Calls Team Worst In NFL

The Arizona Cardinals' Darnell Dockett is out for the season with a knee injury, but the defensive end still managed to rile up opposing fans from the sideline Sunday.

As the Cardinals were defeating the host Oakland Raiders, 24-13, Dockett held up a handwritten sign teasing the Raider faithful that their team is winless. (In fact, the Raiders are now the only NFL team without a victory after Jacksonville won Sunday.)

Dockett later explained his actions, chalking it up to bad fan behavior.

Raiders fans have forged a reputation for rowdy and violent behavior throughout the years, but NBC recently reported there have been more arrests of late among fans of the Raiders' Bay Area rival, the San Francisco 49ers.
