NFL Players Association president Kevin Mawae said in a statement Friday morning that the NFLPA was still "discussing the most recent written proposal with the NFL" but would not be releasing any further statements Friday. The players will be silent for the remainder of the day out of "respect for the Kraft family while they mourn the loss of Myra Kraft." A player vote on the proposed labor agreement owners ratified Thursday is still possible later Friday. Sources told ESPN senior NFL analyst Chris Mortensen that players still want owners to budge on two key issues: -- An opt-out clause seven years into the proposed 10-year collective bargaining agreement. -- The ability to report to team facilities and vote in person on recertifying as a union.
