Per the UFC, the bout was pulled due to COVID-19 protocol issues stemming from Dos Santos' camp. Johns first mentioned the cancellation on Instagram. The two men were scheduled for a bantamweight matchup on the preliminary portion of the card.
"I want to wish him a speedy recovery, want to thank the UFC for the opportunity but mainly want to apologize to everyone who was looking forward to watching me fight today," Johns wrote on Instagram. "I promise you there is nothing I would rather be doing than putting on a show for you all this evening."
Johns (11-1) has won two of three in the UFC and is a former LFA bantamweight champion. Dos Santos (21-8) snapped a two-fight losing streak in his last fight, a first-round submission win over Martin Day last November.
