Pre-season •
November 2, 2017: The majority of the PBA Board of Governors passed a resolution stating that they will no longer support or endorse the renewal of Commissioner
Chito Narvasa's tenure due to "loss of confidence". Representatives from Alaska, Blackwater, Meralco, NLEX, Rain or Shine, Phoenix and TNT attended a special board meeting on November 2 that passed this resolution. Deputy Commissioner and Technical Head Rickie Santos will be the league's officer-in-charge while the board will still tackle who will replace Narvasa as commissioner. Later in the afternoon, the bloc that composes the three San Miguel Corporation (SMC) teams (San Miguel, Barangay Ginebra and Star) as well as independent teams GlobalPort and Kia stated their continued support with Narvasa. Former PBA chairman Robert Non criticized the move done by the seven board members for making a "whimsical" decision in ousting Narvasa and mentioned that the move was unauthorized and non binding as per the league's by-laws. According to the PBA by-laws, a two-thirds vote of its current membership is necessary to remove or appoint a commissioner. Non also criticized the timing of the meeting when the meeting notice was only sent to all board representatives on Monday, October 30. According to the rules, the board representatives should have been notified seven days before the date set for the meeting. Narvasa later called a press conference at the PBA office in Libis and indicated that he will not resign as the commissioner. He is also requesting the seven teams that will not endorse his term renewal to explain the grounds of their "loss of confidence" to the current commissioner. He also stated that he is willing to resign the commissioner post, but after consultation with his family and lawyers, he will hold on as commissioner, given that any move to oust him should follow the rules stated in the league's by-laws. •
