"After two costly celebration penalties earlier in the season, it stands to reason that every member of the Cowboys would avoid showboating after a TD. But even though Marion Barber is a captain and is supposed to be setting an example for teammates, he was penalized for taking his helmet off after scoring a TD against Arizona on Saturday.

Cowboys owner Jerry Jones and interim coach Jason Garrett made sharp comments after the game, and Garrett was still firm about the matter Monday.

"One of the things we wanted to do was address it immediately," Garrett said. "He obviously made a heck of a good run. And he's a very emotional player, but you have to channel those emotions. He was excited about making that play for us in the game and how it could contribute to our success going forward in the game."
