Denver Broncos linebacker Jonathon Cooper was arrested and faces charges of domestic violence.

Cooper, 28, was booked into the Douglas County jail early Friday morning, according to jail records. He faces two charges of domestic violence and one charge of criminal mischief between $300-$1,000.

Cooper was scheduled to appear in court Friday morning. The alleged offense occurred at about 11:15 p.m. Thursday. His bond is listed as $1,000.

Both Cooper and his girlfriend were arrested, according to an affidavit obtained by The Denver Gazette’s news partners 9NEWS.

Cooper’s girlfriend was arguing with Cooper over cheating allegations in his apartment.

She admitted that she grabbed Cooper’s phone from him and threw it across the room, then picked it up to go through it, according to the affidavit.

Cooper then got into a physical struggle with her, grabbed her arm and took his phone back.

She then tried to take the phone back, and Cooper “braced his neck against [her] neck to prevent her from getting his phone,” the affidavit reads.

After the physical struggle was over, Cooper admitted that he told her that he was going to break her phone if she did not leave the apartment, and that he bit her phone when she did not leave, causing “disabling damage,” according to the affidavit.

The Broncos said in a statement to The Denver Gazette that the team is aware of the arrest and is working to gather more information.

Outside linebacker Jonathon Cooper, a seventh round pick by Denver in 2021 out of Ohio State, is entering his sixth season with the Broncos. He was a part-time starter his first two seasons before becoming a regular starter in 2023.

Over the past three seasons, Cooper has 27 sacks and has played a key role on one of the NFL’s best defenses. He received a four-year, $54 million contract extension in November 2024, taking him through the 2028 season. He has a salary-cap number this season of $5.78 million.

Outside linebacker is considered to be Denver’s strongest position, with the Broncos also having two-time Pro Bowl selection Nik Bonitto as a starter and having solid reserve depth in Dondrea Tillman and Jonah Elliss.

The Broncos had their third organized team activities practice Thursday, and Cooper was on the field. The Broncos will conclude offseason drills with another round of organized team activities next Tuesday through Thursday and a mandatory minicamp June 16-18.
