Legendary former champ Matt Hughes suffered a traumatic brain injury a couple years ago when a train struck his vehicle. He recovered, and though there will likely never be designs on him ever returning to the cage, the simple fact that he was able to walk and talk again was nothing short of miraculous.

Unfortunately, according to TMZ, things have taken an ugly, violent turn with Hughes. So ugly and violent in fact that Hughes’ wife and brother have both gotten restraining orders against him.

The TMZ report is below, but when you read it, please keep in mind that violent outbursts and lack of impulse control are textbook after-effects of TBI. Either way you cut it, though, the news is pretty sad.

UFC legend Matt Hughes has been ordered to stay 500-feet away from his wife — who claims Matt has physically attacked her multiple times and once threatened to shoot her.

It’s all part of court docs, obtained by TMZ Sports, in which Audra Hughes describes a disturbing pattern of violence and abusive behavior beginning in 2017.

Remember, the UFC Hall of Famer nearly died when a train struck his truck in a June 2017 accident that left Hughes with a serious brain injury.

But, Audra says shortly after he recovered from the trauma in September or October 2017 … he roughed her up badly in the shower.

Audra claims she refused to give Matt his truck keys, saying, “I told him he can’t have them because he shouldn’t drive due to his DAI (brain injury).”

She alleges Matt then snapped … choked her — and asked her for the code to his gun vault.

When Audra refused again … she says Matt choked her again, smashed her head against the shower wall and screamed, “This is what choking is!”

Audra says nearly a year later on July 21, 2018 … Matt told her, “I’m going to f*cking shoot you,” because she took his phone, claiming, “he was communicating with multiple women.”

Audra also says just a few months later, on Dec. 12, 2018 … Matt hit her in front of her son, their daughter and her step-dad after she accused him of texting other women.

Audra filed for a restraining order the following day … and a judge has since ordered the fighter to stay at least 500-feet away from Audra and their children.
