WBA light flyweight super champion Hiroto Kyoguchi has contracted the novel coronavirus, the Japan Boxing Commission said Monday, and his world title bout on Tuesday has been canceled.

The 26-year-old was to make his third title defense against 10th-ranked challenger Thanongsak Simsri of Thailand, 20, in Osaka. Kyoguchi had been scheduled to make a title defense in May but that bout was canceled due to the pandemic.

The JBC said Kyoguchi's cornerman, who is in his 50s, has also tested positive for the virus in a polymerase chain reaction test. Neither is showing any symptoms and both are in quarantine.
