Former UFC flyweight champion Deiveson Figueiredo was in a scary car accident in Brazil on Thursday ... documenting the aftermath in a social media video -- but thankfully, it sounds like he's all good.
The sixth-ranked bantamweight contender in Dana White's promotion said he was going on a local street in the city of Belém when the collision occurred ... claiming a woman was seemingly "on the run" and driving "at a high speed" prior to impact.
Figueiredo said "thank god we're fine" ... and the other party involved is okay as well.
