Lungiambula initially announced that Roberson had tested positive for COVID-19 on Twitter, and the news has since been confirmed by multiple outlets. According to Lungiambula and other reports, the bout will be rebooked for UFC Fight Night 183 on Dec. 19.
UFC 256 takes place on Saturday at the UFC Apex in Las Vegas and is headlined by a flyweight championship tilt between Deiveson Figueiredo and Brandon Moreno. The event also lost a strawweight scrap pitting Angela Hill against Tecia Torres due to COVID-19 over the weekend.
Roberson had a two-bout winning streak halted at UFC on ESPN 10, where he was submitted in the opening stanza by Marvin Vettori on June 13.
Lungiambula saw a six-fight professional winning streak come to an end in his second Octagon appearance, as he was knocked out by Magomed Ankalaev at UFC Fight Night 163.
