Aaron Monteiro Bio
Aaron Joseph Monteiro (born March 25, 1997) is an American professional football offensive tackle. He played college football at Boston College and has been a member of the Miami Dolphins, New England Patriots, Carolina Panthers, and Washington Commanders of the National Football League (NFL). Listed at 6 ft 6 in and 339 lb, Monteiro has worked as a developmental offensive lineman since going undrafted in the 2019 NFL draft.
After spending time bouncing between practice squads in the NFL, Monteiro transitioned to spring football and signed with the San Antonio Brahmas of the United Football League. In January 2026, he was selected by the Columbus Aviators in the UFL draft, where he continues his professional career as an offensive tackle.
Early Life and Background
Aaron Joseph Monteiro was born on March 25, 1997, in Brockton, Massachusetts. He grew up in the city and attended Brockton High School, where he developed into a Division I offensive line prospect. Monteiro came from a Brockton community that has produced a steady stream of college and professional football talent, and he was rated as a three-star recruit by 247Sports.com coming out of high school.
He committed to Boston College on March 29, 2014, choosing the Eagles over other suitors. Monteiro spent his formative years training as a tackle, building the size and footwork that would later define his professional profile. His progression through the Brockton football system prepared him for the jump to ACC-level competition.
Path to American Football
Monteiro enrolled at Boston College in 2015 and spent four seasons developing within the Eagles program. He worked his way into a starting role along the offensive line and earned third-team All-Atlantic Coast Conference honors in 2018, his senior campaign. That recognition marked him as one of the conference’s top linemen that season and helped raise his profile ahead of the NFL draft process.
Despite his All-ACC nod, Monteiro went undrafted in the 2019 NFL draft. He signed his first professional contract with the Miami Dolphins on May 10, 2019, beginning a steady climb through NFL practice squads. The transition from a Boston College starter to a pro-level developmental prospect required patience, and Monteiro leaned on his college technique to earn opportunities in multiple organizations.
Aaron Monteiro Career
Early Career (2019)
Monteiro’s rookie year was defined by short stints with three different NFL franchises. After signing with the Miami Dolphins on May 10, 2019, he was released on August 21 as the team trimmed its roster ahead of the regular season. Less than two months later, on October 22, 2019, the New England Patriots signed him to their practice squad, though he was released one week later on October 29.
On November 12, 2019, the Carolina Panthers signed Monteiro to their practice squad, giving him his longest initial foothold in the league. He signed a future contract with Carolina on December 30, 2019, securing his place in the organization heading into 2020. That stability allowed Monteiro to focus on adding strength and refining his pass-protection sets.
Carolina Panthers Tenure (2019–2021)
Monteiro’s most extended NFL run came with the Carolina Panthers, where he remained on and off the active roster for three seasons. He was released on September 5, 2020, but was re-signed to the practice squad on September 21, and later promoted to the active roster on December 19, 2020, and again on January 2, 2021. Carolina signed him to a future deal on January 4, 2021, signaling continued investment in his development.
In 2021, Monteiro was released on August 30 but re-signed to the practice squad, then released again on November 3 and re-added on November 9. After his final release from Carolina on May 12, 2022, he moved on to another NFL opportunity. Across his Panthers tenure, Monteiro served primarily as a depth tackle and practice-squad contributor.
Washington Commanders Era (2022–2023)
On May 23, 2022, Monteiro signed with the Washington Commanders, joining another NFC organization in need of offensive line depth. He was released on August 30, 2022, but was re-signed to the practice squad the following day, a familiar pattern for a player whose value came on the developmental side of the roster.
Monteiro remained with Washington through the 2022 season but was released on August 28, 2023, as the team finalized its roster. His time with the Commanders reinforced his standing as a reliable practice-squad tackle with starting-level size.
San Antonio Brahmas Era (2023–2025)
On December 13, 2023, Monteiro signed with the San Antonio Brahmas of the United Football League, beginning a new chapter in spring professional football. The move gave him a chance to compete for a starting role rather than operate solely on a practice squad. He played two games for the Brahmas during his UFL tenure.
Columbus Aviators Era (2026–Present)
On January 13, 2026, Monteiro was selected by the Columbus Aviators in the 2026 UFL draft, joining the league’s newest franchise. The selection marked a fresh start for the veteran offensive tackle and offered an opportunity to compete for a starting spot in Columbus. He is currently listed on the Aviators’ active roster wearing No. 67.
Driving Style and Strengths
At 6 ft 6 in and 339 lb, Monteiro brings prototypical tackle size with the long frame NFL and UFL evaluators look for on the edges. His Boston College background gave him a strong base in pass protection, and he has shown the versatility to play on both sides of the offensive line. Coaches have valued his practice-squad reliability and his willingness to refine technique on a daily basis.
Notable Events and Milestones
Monteiro’s signature career milestone came in 2018 when he was named third-team All-ACC during his senior season at Boston College. Going undrafted in 2019 and still carving out a professional career across multiple NFL practice squads and the UFL stands as a testament to his persistence. His selection in the 2026 UFL draft by the Columbus Aviators marked another step in a journeyman career that now spans more than half a decade.
