Jailton Malhadinho had a rough start at the ACA and, to make matters worse, became the target of mockery from Valter Walker . The Bahia native faced Evgeniy Goncharov, Malhadinho's teammate, and ended up losing by judges' decision. Even before the match, however, Malhadinho had already been the target of provocations from his compatriot.
It all started when Jailton Malhadinho decided to confront Valter Walker . The man from Bahia accused the Rio de Janeiro native, who currently resides in Russia, of mocking Jiu-Jitsu by using the greeting 'oss'.

After the fight, Walker continued to taunt Malhadinho. In a social media post, the Brazilian shared a montage in which his rival appears dressed as a homeless person, begging for money and, ironically, 'respect for jiu-jitsu'.
