NBA bad boy Matt Barnes has been seen spitting on his fiancee’s ex-husband in a heated quarrel at the Dallas Cowboys-San Francisco 49ers game, even though the 2017 NBA champion has claimed that he wasn’t the instigator and was threatened.

The altercation between Barnes and David Patterson Jr., who was previously married to Anansa Sims – the daughter of former model Beverly Johnson – took place at 3.40 pm on Sunday prior to the Niners’ 12-19 win at Levi’s Stadium, according to TMZ.

Footage shows Barnes, an ex-NBA journeyman who last played for the Golden State Warriors, spitting on Patterson – a former NFL defensive tackle – though tensions boiled over afterwards when a group of fans had to separate the two men following an exchange of insults before both parting their own ways.

Barnes said that Patterson had been harassing him for a while, even ‘hunted me down & aggressively confronted me,’ according to an application for a temporary civil restraining order filed through the US District Court for the Central District of California, two days after the incident.

He added that his fiancee’s ex-husband ‘shoved me, and I was forced to push him off me.’

‘I did not want the altercation to physically escalate further, and out of frustration with him seeking me out and his unrelenting harassment I [spat] in his direction in his disgust.’

Barnes also alleged in the court files that Sims’ ex-boyfriend once threatened to shoot him with his ‘glock’ and believes that Patterson Jr. ‘is jealous of my relationship with his ex-wife.’

He also claimed that Patterson Jr. previously threatened to shoot him with his gun in 2022 and that he instigated their quarrel on Sunday by ‘yelling out my full name repeatedly.’

DailyMail.com has contacted Barnes’ lawyer, Jacquelynn L. Hansen, for further comment. In his application for a temporary restraining order, Barnes asked a judge to refrain Patterson Jr. from approaching him within 100 yards of his surroundings.

Police also told TMZ that they were called to Levi’s Stadium to report an allegation of battery. That’s when they identified the 42-year-old former small forward, who had a 13-year NBA career from 2014 to 2017.

In the aftermath of his spat with his fiancee’s ex-husband, Barnes went on to enjoy the 49ers win, as he watched all the game’s action from the stadium’s suite seats.

He and Sims have been dating for five years. The couple got engaged after Barnes proposed on December 26, according to the former NBA player’s Instagram.

Barnes served a two-game ban for attacking and threatening former NBA player Derek Fisher for dating his estranged wife Gloria Govan in 2015.
