Despite the NFL and NFLRA reaching an agreement Wednesday night, early Thursday morning, the officials still had to approve of the deal. If that sounds confusing, think back on the NFLPA deal. Once negotiations reached an agreement and news broke that the players agreed to terms, a vote was still required among the players to approve the deal. Similar situation here.
According to reports officials approved the eight-year deal Saturday morning. Details of the deal that was voted and approved are posted here.
