Dallas Cowboys executive vice president Stephen Jones, a member of the league's business ventures committee, said the league is exploring the possibility of having sponsor logos worn unobtrusively on practice jerseys. In addition to receiving a four-year, $4 billion extension from DirecTV and investigating relaxing rules against liquor and lottery sponsorships, the practice jersey sponsor logos were addressed at the three-day owners' meetings that concluded Wednesday. Further discussion will be held at the league's May meetings in Fort Lauderdale. "It would be similar to logos worn on pro soccer jerseys," Jones said.
