Sincere Haynesworth Bio
Sincere Amaru Haynesworth is an American professional football center who currently plays for the St. Louis Battlehawks of the United Football League. Born on April 13, 2001, in Buffalo, New York, he has built his career along the offensive line, playing every snap of his college seasons at Tulane before working his way through several NFL practice squads and ultimately finding a home in the UFL. Standing 6 feet 1 inch tall and weighing 300 pounds, Haynesworth has earned recognition as one of the most durable interior linemen in his conference during his time with the Tulane Green Wave.
After going undrafted in the 2024 NFL Draft, Haynesworth signed with the New Orleans Saints and began a journey that took him through multiple practice squads, including a brief stint with the New England Patriots. He later signed a reserve/future contract with the Arizona Cardinals before joining the St. Louis Battlehawks in January 2026. His path reflects the resilience and patience required of undrafted linemen trying to establish themselves in professional football.
Early Life and Background
Sincere Amaru Haynesworth was born on April 13, 2001, in Buffalo, New York. Although he was born in upstate New York, he later relocated to Texas, where he attended Pearland High School and developed into a Division I prospect. Coming out of high school, Haynesworth was rated as a three-star recruit and held scholarship offers from Tulane, Army, Navy, Louisiana Tech, North Texas, Arkansas State, and McNeese. The variety of offers reflected the attention he had drawn as a physical, technically sound interior lineman with the footwork and toughness coaches look for along the offensive front.
Haynesworth ultimately chose to commit to the Tulane Green Wave, where he could compete for early playing time and grow within a program that valued trench work. His decision to enroll at Tulane gave him the opportunity to develop under experienced offensive line coaches while representing a Group of Five program with a growing national profile. The move from New York to Texas, and then to Louisiana for college, helped shape the disciplined and adaptable approach he has brought to every level of the sport.
Path to American Football
Haynesworth’s road to professional football began on the high school fields in Pearland, where his combination of size, strength, and intelligence drew the attention of multiple college programs. His three-star rating placed him among the more closely watched interior linemen in his recruiting class, and his scholarship list included service academies as well as regional programs. By the time he signed with Tulane, Haynesworth had already shown the kind of work habits and physical tools that suggested a long career along the offensive line.
At Tulane, Haynesworth quickly established himself as a reliable contributor. He arrived on campus in 2019, played eleven games with five starts as a freshman, and then transitioned from offensive guard to center beginning with the 2020 season. The position change highlighted his football IQ and willingness to do whatever his team needed. His steady development through his first three college seasons prepared him to anchor the middle of the Tulane offensive line as a full-time starter during his final two years.
Sincere Haynesworth Career
Early Career (2019–2021)
Haynesworth began his collegiate career with the Tulane Green Wave in 2019, appearing in eleven games and making five starts as a freshman while playing offensive guard. His early production earned him a starting role, and the coaching staff moved him to center heading into the 2020 season, a transition that showcased his versatility and understanding of protections and assignments. He responded by starting all twelve games during the 2020 campaign and earning Second Team All-Conference USA recognition for his performance at the position.
During the 2021 season, Haynesworth started ten games for the Green Wave, continuing to grow as a pass protector and run blocker from the center spot. He became a consistent presence along the offensive front, anchoring the line of scrimmage and providing leadership in the huddle. By the end of his third college season, he had positioned himself as a foundational piece of the Tulane offense heading into his upperclassman years.
Tulane Breakthrough (2022–2023)
Haynesworth’s senior campaigns represented the peak of his college career. During the 2022 season, he played in and started all fourteen games for the Tulane Green Wave, anchoring the offensive line while facing top American Athletic Conference defensive fronts. His dependability and toughness that season earned him First Team All-Conference USA honors, validating the decision to make him a full-time center two years earlier.
In 2023, Haynesworth started all fourteen games once again, repeating as a First Team All-Conference USA selection. His back-to-back first-team nods confirmed his standing as one of the premier interior linemen in the American Athletic Conference. Across his final two seasons, he never missed a start, giving the Tulane offense continuity and stability at the most important position along the offensive front.
Arizona Cardinals Era (2025)
After spending the 2024 season between the New Orleans Saints and New England Patriots practice squads, Haynesworth signed a reserve/future contract with the Arizona Cardinals on January 7, 2025. The deal gave him an opportunity to compete for a roster spot in his first full offseason with an NFL franchise. He participated in organized team activities and training camp, working to earn a role on the interior offensive line.
Haynesworth was waived by the Cardinals on August 26, 2025, as part of final roster cuts, then re-signed to the practice squad the following day before being released the day after. The brief return showed that the Cardinals valued his experience and wanted to keep him in their system, even if an active roster spot did not materialize. His time in Arizona helped him refine his professional routine and prepare for the next chapter of his career.
St. Louis Battlehawks Era (2026–Present)
On January 23, 2026, Haynesworth signed with the St. Louis Battlehawks of the United Football League, beginning a new phase of his professional career. The move gave him a chance to play in a spring league that has become a proving ground for NFL-caliber talent seeking another route onto NFL rosters. He joined the Battlehawks wearing jersey number 63 and was listed as an active center on the roster.
Joining the UFL allowed Haynesworth to take live game snaps in a professional setting after a year spent almost entirely on practice squads. His experience as a four-year starter at Tulane and his familiarity with multiple offensive systems made him an attractive signing for the Battlehawks. He entered spring camp looking to anchor the middle of the offensive line and help establish the run game for the St. Louis offense.
Driving Style and Strengths
Haynesworth is best known for his consistency, football intelligence, and durability along the offensive line. His ability to start every game across his final two college seasons demonstrated a high level of conditioning and preparation.

Notable Events and Milestones
Among the defining moments of Haynesworth’s career are his two First Team All-Conference USA selections in 2022 and 2023, which made him one of the most decorated Tulane offensive linemen of his era. Going undrafted in 2024 but still reaching a professional roster remains a notable achievement, as do his multiple practice squad signings with the Saints, Patriots, and Cardinals.
