The NFL owners' only definitive action at their meeting was the 27-5 vote to ban the horse-collar tackle, in which a defender grabs the back inside of an opponent's shoulder pads and yanks the player down. Dallas safety Roy Williams does the tackle as well as anybody, but he seriously injured All-Pro receiver Terrell Owens of Philadelphia with the maneuver last season. Dallas Cowboys owner Jerry Jones voted against the change, saying he was concerned about ambiguities in the new rule. A 15-yard penalty will be called only if the tackle immediately brings the ball carrier down, and only if he's in open field. ``I'd rather it had been a fine and it not gotten to the penalty phase,'' Jones said.
