Prosecutors have thrown in the towel in the domestic violence case against George Foreman's son ... TMZ Sports has learned.
We broke the story ... 23-year-old George Foreman the 5th was arrested back in February for allegedly choking his wife during a heated argument at their home in Texas.
But we're told ... in the end, prosecutors just didn't have enough evidence to move forward with a case against him.
"We didn’t think we could prove [that Foreman strangled his wife]," Harris County D.A. spokesperson Lisa Porter tells TMZ Sports.
The D.A. eventually filed docs to drop the case against Foreman and a judge has signed off -- meaning Foreman is officially off the hook.
