Tardiness pushes Dixon to bench

ARLINGTON, Texas -- Ahmad Dixon was the brightest spot on the Dallas Cowboys' defense after the first preseason game with 12 tackles. Being late to Friday's walkthrough cost him a chance to play in Saturday's 37-30 loss to the Baltimore Ravens.

As he attempted to get involved in the walkthrough, he was waved off by coach Jason Garrett and was told before the game he would not play.

"It was real disappointing not to be out there with my teammates and I've been real hard on myself," Dixon said. "I've never missed a game in my life unless I was hurt. I've beat myself up about it."

Dixon missed all but one practice last week because of a concussion suffered in the fourth quarter of the loss to the San Diego Chargers. A seventh-round pick, Dixon may have hurt his chances of making the final roster.

"We had intentions of playing him but you have to handle your business," Garrett said. "You have to be somebody we can trust and hopefully he'll learn from this experience."
