NFL star Earl Thomas is lucky to be alive after cops say his wife held a loaded gun less than a foot from his head … after she allegedly caught him cheating with another woman.

It’s all spelled out in court documents obtained by TMZ Sports … detailing a violent April 13 altercation involving the Baltimore Ravens player, Nina Thomas and several other people.

The Austin Police Dept. responded to a home in the Austin, Texas area at 3:41 AM after getting a call about a disturbance.

When cops arrived, they say “we observed that a black female wearing an orange sweater with a knife in her hand, later identified as Nina Thomas, was chasing a shirtless black male, later identified as Earl Thomas, with a pistol in his hand around a vehicle.”

Cops drew their weapons and ordered both Nina and Earl to the ground — and they complied without incident. That’s when the investigation began and things got WILD.

Here’s Nina’s story, according to court docs …

Nina claims Earl, 30, left their home earlier in the day after an argument over the NFL player’s drinking. She claims Earl’s brother, Seth Thomas, picked him up.

But, a short time later, she decided to check on his whereabouts by logging into his Snapchat account — and that’s when she says she found video of Earl with another woman.

Nina says she used Earl’s Snapchat account to track his location to a nearby Airbnb rental home … and says she called up two other women to help her confront Earl at the pad. Nina also claims she grabbed Earl’s pistol, a 9mm Berreta, in the process with the intention to “scare him.”

When the women arrived at the house, they “discovered Earl and Seth naked in bed with other women.”

That’s when Nina admits she pulled out the gun and put it to Earl’s head — stating “that she took out the magazine thinking that the gun could not fire.” But, cops say Nina was “unaware that the gun had a round in the chamber.”

Cops say one of the women in the house shot cell phone video of the incident … which they say shows Nina pointing the gun at Earl’s head “from less than a foot away and it can clearly be seen that Nina’s finger was on the trigger and the safety is disengaged.”

Fortunately for Earl, cops say the Ravens defensive back was able to wrestle the gun away from her.

Cops say the cell phone video also shows Nina striking Earl in the nose before it ends.

Cops also spoke with Earl, who essentially corroborated the story … adding that Nina repeatedly hit him while he attempted to take the firearm away.

In an interview with Earl’s alleged mistress at the scene, she claimed Nina also threatened her and the other woman in the house — pointing the gun at them and yelling “I got something for all you hoes!”

The woman claims one of Nina’s other friends was carrying a knife and swinging it aggressively during the altercation as well.

After speaking with everyone, cops ultimately arrested Nina and both members of her posse. Nina was booked for burglary of a residence with intent to commit aggravated assault with a deadly weapon — family violence, and later bonded out.

Earl was NOT arrested.

Court records show Nina was also hit with an emergency protective order … requiring her to stay 200 yards away from Earl and his alleged mistress.

As we previously reported, Earl and Nina were married in an extravagant wedding back in April 2016 … Russell Wilson and Ciara even attended the ceremony.

Earl is one of the best defensive players in the NFL — he’s a 7-time Pro Bowl defensive back who won Super Bowl XLVIII as a member of the Seattle Seahawks.

Thomas was a key part of Seattle’s legendary “Legion of Boom” — along with Richard Sherman and Kam Chancellor.

When contacted by TMZ Sports, Nina’s attorney, Jonathan Goins, told us, “I am here to declare that my client unequivocally and categorically denies these allegations and we look forward to our day in court where we can clear her good name.”

We also reached out to Earl Thomas for comment before we published the story — and he released a statement on social media.

“Instead of talking about us, just keep us in y’all prayers,” Thomas says. “Stuff like this happens. We try to live the best lives we possibly can. Sometimes it doesn’t go as planned.”

Bashaud Breeland‘s arrest Tuesday nearly turned tragic … terrifying video of the scene obtained by TMZ Sports shows the NFL player’s face was within inches of a cop’s drawn gun during the stop.

Breeland was detained at around 11 AM at a South Carolina gas station after a York County Sheriff’s Office deputy says he saw the K.C. Chiefs player and 2 other men smoking weed.

The officer claims when he stopped Breeland for questioning … the 28-year-old became combative — and in new footage we obtained from the incident, you can see how the confrontation escalated in a hurry.

In the video, the officer attempted repeatedly to place the Chiefs cornerback in handcuffs … but Breeland consistently refused.

At one point in the vid, you can see the cop pulled a taser on the 5’11”, 195-pound defensive back … ordering him to stop resisting.

“Put your hands behind your back or you will get tased,” the officer said. “Turn around and face away from me! You’ll get tased!”

Breeland, though, ignored the officers orders … and when he wriggled away from the cop and got into his car — things took a frightening turn.

The officer pulled his gun and put it inches from Breeland’s face … and screamed at the NFL player, “Let me see your hands! … I’m not playing!”

Eventually, Breeland got out of the car, got on the ground and ultimately relented to the officer placing him in cuffs.

Breeland was taken to jail without further incident, police records show … and he was booked on 4 charges, including resisting arrest and possession of marijuana.

For his part, Breeland said in a now-deleted post on his social media, “I really was at a gas pump got approach by two guys police pulled up they throw something my car as police pulled up which the cop saw.”

“I was the one detained wit charges that really shouldn’t be charged.”

Breeland’s attorneys added in a statement Wednesday, “At the time of this encounter with law enforcement, Mr. Breeland was leaving a gas station store after making a lawful purchase.”

“Moments after returning to his vehicle, a 2020 Range Rover with valid temporary paper tags, law enforcement officers approached Mr. Breeland and drew their weapons. We look forward to investigating why this level of force was necessary.”

They added, “Bashaud Breeland is innocent unless proven guilty. We look forward to the truth coming forward.”
