Cardinals OG Isaiah Adams arrested on firearm charges in Canada

Arizona Cardinals offensive lineman Isaiah Adams was arrested in his native country of Canada on Sunday on firearm charges, per TSN’s Dave Naylor.

“We are aware of the situation involving Isaiah Adams,” the Cardinals said in a statement to Arizona Sports’ Tyler Drake. “Out of respect for the process, we will refrain from commenting further at this time.”

The report from Durham Regional Police in Canada details that Adams was among four arrested following a Guns and Gangs investigation, a specific unit within the police force.

The investigation concluded on Friday and found a male that was believed to be involved in drug trafficking and in possession of a firearm, per the police report. That suspect and a female were arrested in Ajax, a town within the province of Ontario, in a vehicle that had over three kilograms of fentanyl within it. There was later a search warrant executed at a residence in Pickering, another town in Ontario, where a second female was also arrested without incident.

The loaded firearm was confirmed to be stolen from Georgia in the United States. On Sunday, the fourth suspect, believed to be Adams, turned himself into police, according to the police report.

Adams is charged with possessing a firearm obtained by crime, possessing a restricted/prohibited firearm without a license, possessing a loaded firearm and possessing a prohibited device, per the police report. The firearm in question was a loaded replica Uzi firearm and included a prohibited overcapacity magazine.

All were held for a bail hearing, and TSN reports that Adams’ next court appearance would be on Sept. 1.

Adams is in his third season with the Cardinals after being selected in the third round of the 2024 NFL Draft. He was expected to slot in and emerge as the team’s starting right guard last season, only to struggle with inconsistencies and had an inability to fend off veteran Will Hernandez for the spot. Adams was in a position to be battling with 2026 second-round pick Chase Bisontis for the starting spot in 2026.

Cardinals players will report to training camp on Wednesday.
