One less off-the-field issue for Antonio Brown ... who just struck a settlement with the man claiming Brown nearly killed his child in a crazy furniture-throwing fit. 

We broke the story ... Brown was sued by Ophir Sternberg -- who claims his 22-month-old son was walking around the pool at a high-end apartment complex in Florida in April 2018 when suddenly "large objects started to fall from the building many floors above them."

In his suit, Sternberg claims Brown tossed everything from vases to an ottoman and other pieces of furniture ... and they landed mere FEET from the toddler, who was allegedly traumatized by the whole thing. 

For his part, Brown denied throwing the items -- claiming the tosser was another person who had access to his apartment that day.
