Derrick Ward's wife wants out ... filing court docs to divorce the ex-NFL running back after allegations he's been brutalizing her over the past year.
As we previously reported, Ward's wife Naomi got a restraining order against the former NY Giants running back last month claiming he's been physically abusive in front of their children -- shoving her, punching walls and breaking things.
Now, we've learned Naomi filed for divorce on Feb. 5th in Los Angeles seeking to end the marriage once and for all.
We've reached out to Ward for comment -- so far, no word back.
