IRVING, Texas -- The trade deadline is Oct. 28, but the Dallas Cowboys already feel like they have a big acquisition on the way in rookie defensive end DeMarcus Lawrence. Lawrence will begin his second week of practice on Thursday as he works his way back from a broken right foot suffered in training camp and can make his season debut Nov. 2 against the Arizona Cardinals. On 105.3 The Fan in Dallas on Tuesday, owner and general manager Jerry Jones said Lawrence had “everybody frothing at the mouth,” at practice last week.
