Police have finished their investigation into the youth football game fight where LeGarrette Blount threw punches at a man ... and they've now kicked over the case to prosecutors, who will decide if the ex-NFL player will face criminal charges.
A spokesperson for the Gilbert Police Dept. tells TMZ Sports ... cops turned the case over to the Town of Gilbert Prosecutor's Office for review in the last few days.
It's unclear if the GPD recommended any charges in that handoff.
Prosecutors now have a choice -- file criminal charges against Blount ... or let him off. We've reached out for comment, but so far, we haven't heard back yet.
As we reported, cops initially began their investigation into Blount on Oct. 1, after he was involved in a huge fracas following the conclusion of a 12-year-old-and-under football game in Gilbert, Arizona.
Video, obtained by TMZ Sports, appears to show the three-time Super Bowl winner -- a coach for one of the teams involved in the game -- getting ticked off by something someone said in the postgame handshake line.
In the footage, Blount appears to sprint after somebody -- before throwing two punches at a man.
Cops say they were called to the scene, but the fight had concluded once they arrived. They said no injuries were reported.
Blount eventually apologized for his role in the incident, saying in a statement, "As a leader, coach, father and a role model I understand my actions are unacceptable. I hope and pray for your understanding and forgiveness and plan to continue to be a positive impact in the lives of our youth."
He added that he believes there's more to the story than what the video showed ... but he explained, "Regardless of that, I take full responsibility for my part in it and for putting myself in this situation."
