Former UFC star Nate Diaz has been slammed by one of his sparring partners ahead of his boxing debut against Jake Paul.
Diaz, 38, bowed out of his 27-fight run in the UFC with a submission victory over Tony Ferguson in September. Making his UFC debut in 2007, Diaz steadily built a loyal fan base, which was emphasised through his two-fight series with Conor McGregor, and is now set to step into the boxing ring in August.
The UFC veteran was announced as Paul’s next opponent as the YouTube boxer looks to bounce back from his defeat to Tommy Fury in February. Diaz is making the step up to cruiserweight (200 lbs), having previously competed at 155-170 lbs in his MMA career, but his training has been called into question by Esquiva Falcao, who sparred with Diaz at Robert Garcia’s gym.
