The Arizona Cardinals executed two roster moves on Thursday, June 4, 2026, reshaping the lower end of their 90-man roster just ahead of mandatory minicamp. The team signed veteran defensive back Isaiah Oliver and released kicker Josh Karty, who was a sixth-round draft pick out of Stanford in the 2025 NFL Draft.
Isaiah Oliver, 28, brings six years of NFL experience primarily from his time with the Atlanta Falcons and San Francisco 49ers. Initially starting his career as a cornerback in Atlanta, Oliver transitioned to a hybrid safety/nickel role under the 49ers' defensive scheme. This versatility likely attracted the attention of Cardinals general manager Monti Ossenfort and defensive coordinator Nick Rallis, both of whom prioritize adaptability within the secondary.
Following the signing, the Cardinals' roster features nine cornerbacks and six safeties. Oliver projects mainly as a safety or dime linebacker in sub-packages, providing a seasoned option behind starting safety Budda Baker and a developing group of young safeties that includes Dadrion Taylor-Demerson and Kitan Crawford.
It is important to note that Oliver's signing is separate from the team's kicking situation.
Josh Karty's Departure Ends a Short-Lived Experiment
Josh Karty was drafted in the sixth round in 2025 after an impressive collegiate career at Stanford, where he was the all-time leader in field goal percentage. The Cardinals hoped he would bring stability to a position that had seen frequent turnover since Matt Prater's departure.
However, Karty's tenure with the team lasted only one season. In limited action with the Los Angeles Rams during the 2025 season, Karty went 10-for-15 on field goal attempts (66.7%), a mark that did not secure his role. The Cardinals' assessment through practice and preseason work led them to conclude that Karty was not the long-term solution. His release ahead of mandatory minicamp clears the way for the incumbent kicker, Chad Ryland.
Chad Ryland served as Arizona's primary kicker during the 2025 season, converting 25 of 33 field goals (75.8%) and scoring 111 points. Although not among the elite kickers in the league, Ryland's steadiness earned the confidence of the special teams coordinator and the team's locker room. The Cardinals are betting that stability through a full offseason working with the same snapper and holder will improve Ryland's accuracy closer to the 82-85% mark.
Currently, the Cardinals have only Ryland on the 90-man roster as a kicker, with no backup in place. If Ryland suffers an injury during training camp or prior to the season, the team will need to sign a replacement quickly. Veteran kickers such as Robbie Gould and Randy Bullock remain unsigned and could be options for an emergency signing.
Fit and Role for Isaiah Oliver
Isaiah Oliver's experience over the past two seasons with the 49ers is emblematic of the modern NFL role known as the "big nickel" defensive back. At 6 feet tall and 210 pounds, he offers the size and physicality to cover tight ends in the box while maintaining adequate recovery speed for zone coverage responsibilities.
The Cardinals' defensive scheme under coordinator Nick Rallis emphasizes zone coverages with safety rotations. Oliver's exposure to a similar zone-heavy defense in San Francisco should facilitate a smooth transition to Arizona's system.
While Budda Baker remains the clear leader in the safety room, he is entering his 30th year. The group behind him consists of promising second-year players like Taylor-Demerson and Crawford, along with special teams contributor Joey Blount. Oliver's addition brings experienced depth and a veteran presence capable of starting if needed.
The Cardinals have shown a consistent preference for versatile defenders, especially in secondary roles, under GM Monti Ossenfort's regime. Oliver fits that mold well as a Swiss-army-knife defender who can contribute in multiple coverage roles.
Implications for the 53-Man Roster and Salary Cap
With this signing, the Cardinals remain approximately $35.14 million under the salary cap, according to Over the Cap, indicating that Oliver's addition represents a modest financial commitment unlikely to constrain future moves.
On the kicking front, Ryland now enters training camp as the unquestioned starter. This clarity is designed to boost his confidence but comes without the pressure of a kicking competition. The coaching staff will monitor whether this stability helps or inadvertently leads to complacency.
Oliver's pathway to securing a 53-man roster spot will likely begin on special teams. Though he has accrued 168 career tackles, two interceptions, and 12 passes defensed, his recent seasons have found him in a backup or rotational role. His ability to contribute consistently in coverage units and as a reliable third safety will be key in outcompeting younger players.
Historical Perspective on Kicking Moves
The decision to release a draft-picked kicker after just one season is atypical but not unprecedented. Since the NFL expansion in 1994, only 16 kickers drafted have been released before completing their second season. Most teams generally give kickers at least two years to develop, especially when invested mid-to-late round draft capital.
Karty becomes the latest example of the challenging dynamics in managing NFL rosters. League-wide trends show kickers drafted in rounds 5 through 7 have around a 40% chance of lasting more than two seasons on active rosters. The Cardinals gave Karty an opportunity but ultimately chose to move forward with other options.
The critical factor for Arizona now will be the performance of Chad Ryland in the 2026 campaign. Even a modest improvement in field goal accuracy to the low 80s could translate to an additional win in a competitive NFC West division where every point matters.
Looking Ahead
As the Cardinals approach mandatory minicamp later this month, Isaiah Oliver will be on the field vying to contribute, while Josh Karty will not. The kicking role belongs solely to Chad Ryland for now.
Oliver's blend of experience and versatility adds valuable depth to the secondary room, providing defensive coordinator Nick Rallis with more strategic options on defense packages. Meanwhile, the release of Karty simplifies the kicking situation but places added importance on Ryland's consistency.
With a manageable salary cap situation and a clear roster direction, the Cardinals continue shaping toward a defense-first identity in 2026. How these moves translate to on-field success will become clearer as training camp approaches.
The 2026 offseason for Arizona is off to a focused start with trusted veterans like Oliver supplementing young talent, and a clean kicking competition headed into summer. These decisions highlight the franchise's ongoing commitment to building a versatile, adaptable roster to compete in a high-stakes NFC West.
