Last March, Clay Guida called out Nate Diaz for a rematch to take place at UFC 225 this June. This matchup did not end up materializing, but the two fighters ended up going at it with each other, according to reports, at least.
As confirmed in a report by MMA Fighting, the fracas happened during the Combate Americas event on Friday in Sacramento, where Diaz was present to show support to teammate one-time UFC fighter Chris Avila. Guida, meanwhile, was at the event with TUF 27 contestant Tyler Diamond to show support for teammate Anthony Avila.
