Bickley has a little more info on the locker room fight..
Moments after a loss that ceded the NFC West crown to the surging Seahawks, the somber morgue of a locker room suddenly was pierced by linebacker Darryl Blackstock, who became incensed at teammate Darnell Dockett.
What prompted Blackstock's outburst was unclear, but he called Dockett a very bad word at a very high decibel level, telling the teammate that he didn't know who he was dealing with and threatened to mess him up.
As the teammates were restrained, one Cardinals player said to no one in particular, "That's exactly why we got our (backsides) whipped."
It was tough to tell who was more shocked about the in-fighting, the horde of media already in the room or the wide-eyed general manager standing off in the corner. To his credit, Cardinals coach Ken Whisenhunt immediately paid a visit to Dockett, and tempers calmed.
"Words were exchanged," Dockett said. "There's emotion when you lose a game you think you should win. . . . it's nothing."
