## Mixed martial arts career
### Early career

### Ultimate Fighting Championship

Abreu made his UFC debut at light heavyweight against Magomed Ankalaev on 23 February 2019 at UFC Fight Night: Błachowicz vs. Santos. He lost the fight via unanimous decision.
Abreu then faced Sam Alvey on 20 July 2019 at UFC on ESPN: dos Anjos vs. Edwards. He won the fight via unanimous decision.
Abreu next faced Shamil Gamzatov on 9 November 2019 at UFC Fight Night: Magomedsharipov vs. Kattar. He lost the fight via split decision.
Abreu was initially targeted to face Gadzhimurad Antigulov on 13 June 2020 at UFC Kazakhstan. Subsequently, the Kazakhstan event was later cancelled due to the COVID-19 pandemic. As a result, Abreu was rescheduled to face Jamahal Hill on 30 May 2020 at UFC on ESPN: Woodley vs. Burns. He initially lost the fight via technical knockout in the first round, but the fight was later overturned on 3 September because Hill tested positive for marijuana.
On 10 August 2020, it was announced that the UFC released him.

### Professional Fighters League

On 1 June 2021, it was announced that Abreu was signed by the PFL and he made his debut on 25 June 2021 at PFL 6 against Jamelle Jones. He lost the bout after being knocked out in the first round.
Klidson was scheduled to face Ali Isaev on April 28, 2022, at PFL 2. However, Isaev pulled out of the bout and was replaced by Adam Keresh. He won the bout via unanimous decision.
Klidson faced Renan Ferreira on June 24, 2022, at PFL 5. In an upset, Klidson won the bout via unanimous decision. The Georgia Athletic and Entertainment Commission overturned the result of the bout to a no contest, after Abreu failed a drug test for unspecified substances. Klidson and his team contended that the positive was due to prescribed antibiotics for a leg laceration.
