The Arizona Cardinals family is mourning a heartbreaking loss today. Former defensive end Josh Mauro has passed away at the age of 35, his family announced on April 28, 2026.
Details surrounding his death remain private, and the family has requested privacy during this difficult time. No cause of death has been released. What is clear, however, is the profound impact Mauro had during his five-year NFL career--and the even deeper mark he left on the people who knew him.
For Cardinals fans of the mid-2010s, Mauro was the kind of player who embodied the identity Bruce Arians built in the desert. He wasn't the flashiest name on the roster, but he was a steady, reliable presence on a defensive line that helped transform Arizona into a contender.
From Stanford to the Desert
Mauro was originally signed by the Pittsburgh Steelers as an undrafted free agent out of Stanford in 2014. A team captain for the Cardinal, he carried the pedigree of a program that prides itself on toughness and discipline--traits that translated immediately to the NFL level.
After a brief stint on the Steelers' practice squad, Mauro was signed off waivers by the Arizona Cardinals in September of his rookie season. It was a move that would define his professional career.
From 2014 through 2016, Mauro appeared in 43 games for the Cardinals, making 26 starts. He recorded 67 tackles, three sacks, and three passes defensed while serving as a run-stuffing defensive end in Arizona's 3-4 base scheme. The numbers alone do not tell the story. At 6-foot-6 and 280 pounds, Mauro was a long, physical presence who set the edge against the run with surprising power for someone who had to battle against double teams regularly.
He was one of those players that offensive coordinators had to account for--a grinder who didn't make many highlight reels but consistently put his teammates in position to make plays.
A Key Role in the 2015 Run
The 2015 season remains one of the most memorable in franchise history. The Cardinals went 13-3, captured the NFC West crown, and came within a game of reaching Super Bowl 50. Mauro started 14 of 16 games that season, anchoring the defensive line alongside Calais Campbell, Corey Peters, and Frostee Rucker.
That defense ranked fifth in the NFL in points allowed and second against the run. Mauro was a significant part of that success. His ability to occupy blockers, allowing edge rushers like Chandler Jones (who arrived later) and Markus Golden to work one-on-one, was a quietly vital component of defensive coordinator James Bettcher's scheme.
He wasn't asked to be a star. He was asked to be dependable, physical, and selfless. He delivered.
Toughness Personified
One of the defining moments of Mauro's time in Arizona came during the 2016 season. In a Week 7 matchup against the Seattle Seahawks, Mauro suffered a calf injury early in the game. He briefly left the field, got taped up on the sideline, and returned to action--finishing the contest despite being visibly limited.
It was that blue-collar mentality that endeared him to teammates and coaches alike. The Cardinals' front office valued him not just as a player but as a culture-setter in the locker room. Mauro was known for being one of the first to arrive at the facility and one of the last to leave, studying film, working on technique, and mentoring younger players.
In an era where roster turnover is constant, Mauro was a steadying presence. He never complained about his role, never sought the spotlight, and never put himself ahead of the team.
Continuing the NFL Journey
After his initial three-year run in Arizona, Mauro signed with the New York Giants in 2017, where he played two seasons. He recorded 23 tackles and a sack in his first year with the Giants, then appeared in 12 games in 2018 before injuries began to take their toll.
He briefly returned to the Cardinals in 2019, appearing in six games and recording an additional tackle. It was a homecoming of sorts, though his time back in the desert was cut short by a quadriceps injury that ultimately landed him on injured reserve.
Mauro's final NFL game came in 2019. In total, he appeared in 69 career regular-season games, starting 30, and accumulated 94 tackles, four sacks, and five passes defensed across stints with Arizona, Pittsburgh, and New York.
Life After Football
Following his playing career, Mauro largely stepped away from the public eye. Those who remained close to him describe a man who had found peace and purpose in his post-football life. He spent time with family, traveled, and stayed connected to the game through informal mentorship of younger defensive linemen.
He remained close with several former Cardinals teammates, and news of his passing has reverberated through the NFL community. Tributes have poured in from across the league--not just for the player he was, but for the person he was off the field.
Former teammate Calais Campbell posted on social media: "Heartbroken to hear about Josh. One of the toughest, most genuine guys I ever lined up next to. Praying for his family. Rest easy, brother."
Markus Golden, who played alongside Mauro on that 2015 squad, wrote: "Can't believe this. Lost a real one. Josh was a warrior on the field and an even better person off it. My love goes out to his family."
A Deeper Reminder
Mauro's passing at age 35 is a sobering reminder of the fragility of life, even for elite athletes. Players in their 30s are often viewed as near-superhuman--still young, still in peak condition by most standards. But the NFL grind takes a toll that is not always visible on Sundays.
The cause of death has not been disclosed, and speculation serves no purpose. What matters is honoring a life that was lived with purpose, toughness, and grace.
For Cardinals fans, Josh Mauro represented the best of what that gritty, competitive era of Arizona football was all about. He was not a household name, but he was respected in every huddle he ever joined. He earned the right to be remembered.
The Cardinals Family Mourns
The Arizona Cardinals organization released a statement expressing condolences:
"We are deeply saddened by the passing of former Cardinals defensive end Josh Mauro. Josh was a beloved member of our organization and a key contributor to some of the most successful teams in franchise history. He played the game with passion, integrity, and a team-first mentality that earned him the respect of coaches, teammates, and fans. Our thoughts and prayers are with his family and loved ones during this incredibly difficult time."
Flags in and around State Farm Stadium were lowered to half-staff as the organization took time to process the loss.
Final Thoughts
Josh Mauro played 69 NFL games. He had 94 tackles. He was never a Pro Bowler, never a household name, never on a highlight reel that went viral. But he was what the NFL is really built on--tough, dedicated, selfless players who do the unglamorous work that wins games.
He was a Stanford captain. A Cardinal. A Giant. A Steeler. But before all that, he was just a kid from Dallas, Texas who had a dream and chased it all the way to the highest level.
He made it.
And for those who knew him, that was never the question. The question was always about the kind of man he would be along the way. By every account, Josh Mauro answered that question with excellence.
Rest in peace, Josh. You will not be forgotten in the desert.
