Deiveson Figueiredo, who is scheduled to fight Joseph Benavidez for the vacant flyweight title July 18, has tested positive for COVID-19, per ESPN's Marc Raimondi.
Figueiredo's manager, Wallid Ismail, confirmed the news to Raimondi and also said the fight is not officially off. The fighter's team believes the test was a false positive, and he will be undergoing another test on Saturday.
Figueiredo previously tested positive for COVID-19 in May.
Per Raimondi, if Figueiredo isn't cleared to fight, then either Alexandre Pantoja or Askar Askarov could step in as a replacement. The two featherweights are scheduled to fight each other July 18 as well.
