The fracas between Gilas Pilipinas and the Australia national basketball team in Bulacan on Monday may have shocked casual basketball fans but in-game violence is not uncommon in the sport, especially involving local teams.

The following are a few extreme examples of games involving violent, on-court outbursts.

Philippine national team vs Minnesota Division 1 team

The Philippine national side coached by Tim Cone was in the US for a series of tune-ups against NCAA Division 1 teams in preparation for the Asian Games.

One of those games was against University of Minnesota, played on November 16, 1998, one that featured punching, kicking, shoving, players piling one on top of the other and a referee crawling out of the mayhem.

Mapua vs Emilio Aguinaldo College, NCAA

On September 22, 2014, players of the Mapua Cardinals and the Emilio Aguinaldo College (EAC) Generals engaged in a free-for-all with just 28.5 seconds to go in their NCAA Season 90 men's basketball game at San Juan Arena.

EAC was in control, 86-77, when John Tayongtong bumped into Mapua's CJ Isit at halfcourt.

Mapua's Hesed Gabo responded by elbowing Tayongtong, and the situation escalated when Tayongtong threw a punch that sent Isit to the floor.

Benches cleared, as players from both teams spilled onto the court, with the referees, arena security and coaches trying to put a stop to the melee.

TNT vs Rain Or Shine, PBA

On April 22, 2015, an altercation between Matt Ganuelas-Rosser, then of TNT, and Jireh Ibañes of Rain Or Shine in Game 4 of the PBA Commissioner's Cup finals led to players emptying the benches.

JR Quiñahan was seen hurling the ball at Rosser, while Ivan Johnson retaliated. The rest of the players jumped into the fracas.

Presto vs Añejo, PBA

On December 11, 1988, players of Presto and Añejo came to blows when Philip Cezar was fouled hard by Añejo's American player Tommy Davis.

Tension arose and officials stepped in to restrain Cezar. However, Añejo's other US player, Joe Ward, must have heard something from Cezar prompting him to chase Cezar.

A free-for-all erupted with chairs being thrown and coins being hurled onto the court in what many consider to be the worst case of on-court violence in league history.

Marc Pingris vs Kelly Nabong, PBA

On September 4, 2013, Marc Pingris of San Mig Coffee and GlobalPort's Kelly Nabong threw punches at each other, an incident that got so bad coach Tim Cone had to step in and pull a rampaging Nabong down to the ground.

The play that preceded that involved Joe DeVance decking Marvin Hayes, Nabong's teammate, with a two-handed push, an act to which Nabong, coming to Hayes' defense, was reacting.

La Salle vs FEU, UAAP

On August 25, 2017, a full-blown riot erupted between De La Salle University and Far Eastern University players during a tune-up game at Almendras Gym in Davao City.

The game became intense when FEU's Ron Dennison was ejected following 2 unsportsmanlike fouls. On his way out, he was still able to punch La Salle's Kib Montalbo, leading to the free-for-all.

The game was stopped with 20 seconds left in the third quarter and FEU leading 70-57.
