Haggai Ndubuisi Bio
Haggai Chisom Ndubuisi, born on 15 October 2000, is a Nigerian professional American football defensive lineman competing in the National Football League (NFL). Standing 6 ft 6 in tall and listed at 298 lb, he plays the nose tackle position and is recognized as one of the few Nigerian-born athletes to climb the NFL ranks through the International Player Pathway (IPP) program. He is currently a member of the Houston Texans.
Ndubuisi entered professional football in 2022 as an undrafted free agent allocated through the IPP and has since appeared on the rosters of multiple NFL franchises, including the Arizona Cardinals, Denver Broncos, Washington Commanders, and New England Patriots. He also spent time with the United Football League’s San Antonio Brahmas, gaining experience at both the NFL and spring football levels.
Early Life and Background
Haggai Chisom Ndubuisi was born in Lagos, Nigeria, and grew up in a country where American football had almost no presence. As a youth, he played soccer and basketball, the two dominant organized sports available in his community. His introduction to gridiron football came at the age of 18, when he watched a YouTube video showcasing the NFL’s most powerful hits.
Captivated by the physicality of the game, Ndubuisi began gathering friends at local fields to re-enact the plays he had seen, despite having little to no understanding of the rules or structure of American football. He has openly described the sport as one “without hope” in Nigeria, noting that there was effectively no infrastructure or professional pathway for the game in his home country at the time. He often trained alone because organized football was nearly impossible to find.
His raw athletic potential eventually caught the attention of Ejike Ugboaja, who co-leads the UpRise Academy alongside former NFL defensive end Osi Umenyiora. UpRise Academy is a program designed to identify and develop African football talent. Ndubuisi was invited to join the academy in 2021, an opportunity that redirected his athletic future.
Path to American Football
After six months of intensive training with UpRise Academy, Ndubuisi was invited to an NFL camp held in London in late 2021. The experience provided his first exposure to high-level American coaching and competition, and he supplemented that work with private training under former NFL offensive lineman LeCharles Bentley, who helped him refine the technical fundamentals required for the professional trenches.
His progression through the IPP pipeline was swift. Within roughly a year of his first contact with organized football, he was selected as one of the program’s participants for the 2022 NFL cycle, an achievement that positioned him for a chance at an NFL roster despite the absence of a traditional college football background.
Haggai Ndubuisi Career
Early Career (2022)
Ndubuisi’s professional career began in 2022 when he was allocated to the Arizona Cardinals through the International Player Pathway Program, initially listed as an offensive tackle. He made his preseason debut in the Cardinals’ first exhibition game, appearing on two offensive snaps, but was released on 14 August 2022 as the team trimmed its roster.
Although his time in Arizona was brief, the experience validated his potential and set the stage for a return to the IPP the following season. The Cardinals stint marked his first official NFL game action and confirmed that his physical tools could translate to professional-level competition.
Denver Broncos Breakthrough (2023)
In 2023, Ndubuisi was re-allocated through the IPP, this time to the Denver Broncos, and the organization shifted him to the defensive line, a position better suited to his 6 ft 6 in, 298 lb frame. The move paid immediate dividends, as he posted two tackles in his first preseason game with the Broncos, demonstrating both his athletic upside and his ability to contribute on defense.
He was waived on 29 August 2023 as part of the Broncos’ final cuts, but he was quickly re-signed to the team’s practice squad. Although Denver did not offer him a reserve/future contract at the end of the season, his production during the preseason cemented his status as a legitimate professional prospect.
UFL and Washington Commanders (2024)
On 1 February 2024, Ndubuisi signed with the San Antonio Brahmas of the United Football League, joining the spring football circuit to gain additional game experience. His time with the Brahmas was short, as he was waived on 12 February 2024, but the brief stint reflected his continued pursuit of on-field reps.
He returned to the NFL on 3 April 2024, signing with the Washington Commanders. He remained with Washington through the preseason before being waived on 27 August, then immediately rejoined the organization on its practice squad the following day, a common path for developing IPP players seeking to extend their NFL careers.
New England Patriots and Washington Return (2025)
On 1 January 2025, the New England Patriots signed Ndubuisi to their active roster, offering him a brief opportunity at an NFL game-day 53-man spot. He was waived the following day, however, with a non-football illness designation, ending his short Patriots tenure.
Seven days later, on 7 January 2025, he signed back with the Washington Commanders’ practice squad, only to be placed on injured reserve the following day. The sequence illustrated the day-to-day volatility that IPP players often navigate while trying to establish themselves in the league.
Houston Texans Era (2025–Present)
On 31 July 2025, Ndubuisi signed with the Houston Texans, marking his latest NFL opportunity. He was waived on 26 August as part of the Texans’ final roster cuts, then re-signed to the team’s practice squad, a path that has become familiar for him as he works to secure a stable roster spot.
Notable Events and Milestones
Among the most notable milestones in Ndubuisi’s career is his status as one of the few Nigerian-born players to appear in an NFL preseason game. He has logged at least one official NFL game played in his career statistics, and his movement from offensive tackle to nose tackle reflects a successful positional transition that has helped extend his professional longevity.
Haggai Ndubuisi Career Stats
Ndubuisi’s professional resume includes preseason appearances with the Arizona Cardinals and Denver Broncos, practice-squad stints with the Broncos, Washington Commanders, and Houston Texans, and a brief UFL appearance with the San Antonio Brahmas. His career NFL statistics include one regular-season game played, a figure that reflects the practice-squad-driven nature of his developmental path.
Haggai Ndubuisi Family
Personal Life
Haggai Chisom Ndubuisi was raised in Lagos, Nigeria, where he grew up far from the typical American football pipeline. Public information about his immediate family and personal relationships has not been widely reported, and details about a spouse or children have not been confirmed in available sources.
2025 Season Performance
Ndubuisi’s 2025 campaign has been defined by roster movement rather than extensive regular-season game action. He split time early in the year between the New England Patriots and the Washington Commanders’ practice squad, navigating waiver periods and an injured-reserve placement before joining the Houston Texans on 31 July 2025.
With the Texans, he appeared in preseason activity before being waived on 26 August as part of final cuts, only to be re-signed to the practice squad the same day. That bounce-back signing offered him a chance to continue developing within Houston’s program while remaining eligible for elevation to the active roster during the regular season.
Looking ahead, Ndubuisi’s outlook for the remainder of 2025 centers on stability. As an IPP-allocated defensive lineman with multiple NFL camps under his belt, his path to a sustained 53-man roster spot likely depends on continued growth on the defensive line and the ability to contribute on special teams. His journey from Lagos to the NFL remains one of the more distinctive international stories in the modern league.
