Hostilities between the two camps are renewed ahead of the pay-per-view showdown in China.
In 2010, a former opponent of Pacquiao's, Antonio Margarito, was seen to be mocking five-time Futch-Condon award-winning trainer Freddie Roach on camera. At the time, Robert Garcia was coaching Margarito and is the head cornerman in Rios' camp who, too, was also seen in the clip.
Now another video has emerged that seems to show Alex Ariza mocking Roach's suffering of Parkinson's disease before kicking him in the chest. Roach, however, had apparently made remarks that could be seen to be derogatory toward Mexicans and then Jews.
Robert Garcia complained of being called a: 'piece of s***' and Roach could also be heard calling another member of Rios' camp a 'Mexican mother-f*****'.
The incident, filmed today at a gym that both camps intended to use for a work-out ahead of their showdown at the Cotai Arena in the Venetian Resort, Macao, China, mars what is widely regarded to be one of the marquee fights of the year on Saturday, November 23.
Speaking after the incident, Garcia put it down to nerves from Pacquiao's team, alluding to the fact that he thinks they may well have bitten off more than they can chew by selecting Rios for a dogfight in their comeback from two consecutive losses.
If Pacquiao loses a third time, it may well spell retirement for the Filipino icon…
