Pre-season • Several players were sanctioned by their respective teams and the PBA due to numerous
ligang labas infractions. • Due to the long off-season, the PBA launched the "PBA on Tour", a months-long series of pre-season games involving all PBA teams played across the country. Each team played 11 games and were allowed to have 17 players in their roster (but only 16 are allowed to play in a game) which are composed of regular players,
3x3 affiliate team players, free agents, and rookie aspirants. The tour was held from May 21 to July 30, 2023; there was no playoffs nor a championship series. The
Magnolia Chicken Timplados Hotshots finished the tour with the best record, winning all of their 11 games. • During the PBA on Tour,
TNT Tropang Giga retired the jersey number of
Harvey Carey (#4). • The PBA competition committee proposed several rule changes, most notably the addition of the
head coach challenge. • The PBA Board of Governors relaxed its rules regarding draft-eligible players who refuse to enter the draft and active PBA players who leave the league to play in another league locally or internationally. These players are no longer required to "sit out" seasons prior to joining the PBA. The former rule sanctioned these players by barring them from playing in the PBA for at most five years. Foreign-born Filipinos older than 30 years old are also now allowed to join the draft. • The
East Asia Super League disbanded the
Bay Area Dragons on September 1, 2023, reportedly due to financial reasons. The EASL mentions "conflict of interest" for managing a team and organizing the league at the same time, as the official reason for dissolving the club. • The PBA entered into an acquired agreement with
ZOE Broadcasting Network and
ABS-CBN Corporation to air the league's games on
A2Z. All the
ABS-CBN programs were temporarily affected by the changes in programming; A2Z's primetime, afternoon and weekend programming are preempted to give way for the PBA games on Wednesdays, Fridays and Sundays. Previously, the games were formerly broadcast on
TV5.
