Standing 6 feet 4 inches tall and listed at 118 kilograms, Jonathan has built his career on a relentless motor and a developmental path that began in Nigeria and continued through prep football in Baltimore and college play at Syracuse University. After going unselected in the 2022 NFL Draft, he signed with the Buffalo Bills as an undrafted free agent and was also taken first overall by the Montreal Alouettes in the 2022 CFL Global Draft.
Over the course of his professional career, Jonathan has spent time with the Buffalo Bills, Chicago Bears, Houston Texans, and New York Jets, working primarily as an edge rusher and rotational defensive end. While his tenure on NFL active rosters has been marked by short stints, his perseverance has carried him back onto practice squads and into multiple opportunities to compete at football’s highest level.
Early Life and Background
Kingsley Jonathan was born on April 28, 1998, in Lagos, Nigeria, before later relocating to the United States as a young man. He grew up in Baltimore, Maryland, where he attended Saint Frances Academy, a program known for producing NFL-caliber talent. Jonathan also spent time at Eastern Alamance High School, broadening his football exposure during his formative years. In addition to playing defensive end and linebacker, he participated in basketball, soccer, and track and field, developing the kind of athleticism that would later define his professional profile.
As a senior at Saint Frances Academy, Jonathan was a force on the defensive line, recording 65 tackles and 16 sacks while leading his team to a 10-2 record and the MIAA Class A championship. Recruiting analysts took notice, ranking him as the 24th-best defensive end by Rivals.com and the 29th weakside defensive end according to 247Sports. His combination of size, production, and versatility made him one of the more intriguing defensive prospects along the East Coast heading into the college recruitment cycle.
Path to American Football
Jonathan committed to Syracuse University and made his college football debut in 2017 against Central Connecticut, appearing in eight games as a freshman and recording four tackles. The adjustment to college-level competition was gradual, but by his sophomore season in 2018 he had earned a larger role, playing in all 13 games with two starts and posting 21 tackles along with five sacks that placed him third on the team in that category. He was also recognized on the ACC honor roll, an early sign of his commitment off the field as well as on it.
In 2019, Jonathan served as a reserve defensive end and made 12 appearances, recording 24 tackles, three tackles for loss, and 1.5 sacks while earning All-ACC Academic honors. The 2020 season marked a major step forward: he was awarded the Jim Tatum Award as the top student-athlete in the ACC, started all 11 games, and finished with 32 tackles, three sacks, and a forced fumble. He was a Campbell Trophy semifinalist, appeared on the Wuerffel Trophy watch list, and was a Senior CLASS Award candidate. After receiving an extra year of eligibility in 2021, Jonathan returned for a fifth season, appeared in all 12 games with one start, and recorded 20 tackles and 4.5 sacks. He won the Joseph Alexander Award for excellence in football, scholarship, and citizenship, capping a Syracuse career that included 101 tackles (60 solo), 21.5 tackles for loss, 15 sacks, two fumble recoveries, and three forced fumbles across 56 games.
Kingsley Jonathan Career
Early Career (2022)
After going unselected in the 2022 NFL Draft, Kingsley Jonathan signed with the Buffalo Bills as an undrafted free agent, opening his professional chapter with a stable organization known for developing defensive linemen. He was also selected first overall by the Montreal Alouettes in the 2022 CFL Global Draft, but chose to remain in the NFL with Buffalo, signaling his commitment to the American league pathway. On August 30, 2022, he was released as part of final roster cuts, marking the first of several in-season transactions that would define his rookie year.
On September 1, 2022, Jonathan was claimed off waivers by the Chicago Bears, giving him an opportunity with a new defensive staff. He appeared in five games and recorded four tackles before being waived on November 15, 2022. Just two days later, on November 17, the Buffalo Bills signed him to their practice squad, allowing him to return to the organization that had first developed him at the professional level. On January 23, 2023, he signed a reserve/future contract with Buffalo, securing a path back to the offseason roster.
Buffalo Bills Era (2023-2024)
Kingsley Jonathan’s second stint with the Buffalo Bills spanned two seasons and reflected the journeyman rhythm that often characterizes young pass rushers trying to break through. After signing his reserve/future deal in early 2023, he continued to develop within the Bills’ defensive system, working primarily as an edge rusher and rotational piece. On August 27, 2024, Jonathan was released by the Bills as part of final roster cuts, but he was re-signed to the practice squad the following day, preserving his place within the organization.
Throughout this period, Jonathan focused on refining his technique against the run and developing the kind of counter moves required to pressure NFL quarterbacks. While the Bills did not publicly promote him to a starring role during this stretch, his persistence allowed him to remain under contract with one of the league’s most consistent franchises.
Houston Texans Era (2025)
On February 7, 2025, Kingsley Jonathan signed with the Houston Texans, joining a defensive front that had been retooled during the offseason. The opportunity represented a fresh start with a new defensive scheme and coaching staff, and Jonathan entered training camp looking to compete for a depth role along the edge. His time in Houston, however, was brief, as he was waived on May 21, 2025, during the early stages of roster construction ahead of the 2025 season.
New York Jets Era (2025-Present)
On June 12, 2025, Jonathan signed with the New York Jets, beginning what became his most active offseason with a franchise to date. He participated in organized team activities and training camp, working under the Jets’ defensive staff in a bid to earn a roster spot. On August 26, 2025, he was waived as part of final roster cuts, but his career arc would continue when, on November 5, 2025, he was signed to the Buffalo Bills’ practice squad. Just six days later, on November 11, he was released, and on December 9, 2025, he signed back with the New York Jets’ practice squad, where he remained as the season wound down.
Notable Events and Milestones
Among Kingsley Jonathan’s most significant career moments is his selection as the number one overall pick in the 2022 CFL Global Draft by the Montreal Alouettes, an honor that reflected the high regard in which his athletic profile was held internationally. His Jim Tatum Award win in 2020, recognizing him as the top student-athlete in the Atlantic Coast Conference, stands as a defining off-field milestone, while his Joseph Alexander Award at Syracuse underscored his commitment to scholarship and citizenship alongside football.
Kingsley Jonathan Career Wins
College and Professional Highlights
Kingsley Jonathan’s most celebrated competitive achievements came during his college career at Syracuse University, where his production on the field steadily grew across five seasons. His senior-year totals of 32 tackles, three sacks, and a forced fumble coincided with All-ACC Academic honors and the prestigious Jim Tatum Award, marking him as one of the top student-athletes in the conference. He closed out his Syracuse tenure with 101 tackles, 15 sacks, and three forced fumbles, totals that positioned him as a productive edge defender even without a signature single-game signature win at the professional level.
At the professional level, Jonathan has not yet recorded a celebrated regular-season win as a starting defensive end, though he has contributed tackles in limited appearances with the Chicago Bears and has remained a consistent presence on practice squads with the Buffalo Bills and New York Jets. His resume to this point is defined more by perseverance and roster movement than by headline statistical production.
