Tim Tszyu has lashed Errol Spence Jr as a "diva" caught up in his own world after the American was a no-show for a TV appearance to promote the pair's looming Sydney blockbuster.
Spence left Tszyu stranded in a Sydney television studio on Thursday, failing to front for a scheduled satellite cross that had been locked in as fight-week build-up for their July 26 showdown at AfterPay Arena.
