UAAP Season 66 men's basketball tournament

After a UAAP Board decision that upheld the UE Red Warriors' protest against the DLSU Green Archers, three teams ended tied for first after the elimination round.

Results on top and to the right of the dashes are for first-round games; those to the bottom and to the left of it are second-round games.Since Ateneo, FEU and UE finished the eliminations with identical 11-3 cards, the quotient system was used.

Olan Omiping hit a shot to start a 21–4 UE run, that was ended by RJ Masbang when he scored on a three-point play to cut FEU's lead to one point.

With former Chicago Bulls player Scott Burrell at court side, Ateneo led for much of the game; La Salle top scorer Mark Cardona was injured.

With 1:31 left in the overtime period, a bench-clearing brawl erupted after Gaco bumped LA Tenorio after a loose-ball scramble.

After commissioner Joe Lipa and Araneta Coliseum personnel restored order, referees thrown out Ateneo's Magnum Membrere and La Salle's Ryan Araña.

Yeo, who scored 31 points, and JV Casio led La Salle at the end of overtime to extend the series.

At the fourth quarter, as Ateneo's shot clock was running out, center Paolo Bugia made an improbable three-pointer to pad their lead 63–59.

Uniformed policemen, including the SWAT team, and Araneta Coliseum security guards restored order.

RJ Rizada and Gerald Jones scored baskets late in the game to eliminate the Red Warriors anew.
