The labor negotiating teams headed by NFL commissioner Roger Goodell and DeMaurice Smith, the chief of the NFLPA, met for a couple of hours Friday. The two sides will return to the table after the July 4 weekend. They held a 15-hour session Thursday that spilled over into the early hours Friday. After taking a six-hour break to catch some sleep, the sides met again but by late morning left the office building where talks were being held. When the owners and players appeared close to an agreement in mid-June, mid-July was mentioned as a possible end for the lockout.
