UFC president Dana White held Diaz back as the fighters exchanged words, though no additional punches were thrown.
The fighters’ training camps had been a major subject of the trash talk during the news conference with each lobbing critiques about the other’s training partners and methods.
Diaz’s team, which includes his brother and fellow UFC star Nick Diaz, was restrained on one side of the stage inside the David Copperfield Theatre.
McGregor’s team also came on stage, but security intervened and ensured no further escalation.
The welterweight bout headlines a pay-per-view card on Saturday night.
