How a Canadian passport transformed Alex Singleton from an undrafted rookie into an NFL captain.
In short: Alex Singleton spent years bouncing between NFL practice squads before a strategic move to Canada redefined his career. By securing dual citizenship, he bypassed restrictive roster rules, dominated the CFL, and returned to the NFL as a defensive powerhouse. His journey highlights how unconventional paths can lead to elite success.
Born in 1993, Alex Singleton began his professional journey as an undrafted free agent with the Seattle Seahawks in 2015. After being released by Seattle, he spent brief stints with the New England Patriots and Minnesota Vikings, struggling to secure a permanent spot on an active NFL roster. His career trajectory shifted in 2016 when he was drafted by the Calgary Stampeders of the Canadian Football League. Because his mother was born in Toronto, Singleton obtained a Canadian passport, which allowed him to be classified as a national player under specific league rules. This status proved pivotal, as it provided him the consistent playing time he needed to develop.
In the CFL, Singleton quickly emerged as a defensive force. By 2017, he was a nominee for the league's most outstanding player awards, setting a Calgary Stampeders record with 121 tackles. His success in Canada served as a springboard back to the NFL, where he joined the Philadelphia Eagles in 2019. He eventually became a team captain and a consistent leader in tackles, even tying an NFL record with 19 solo tackles in a single game against the Los Angeles Chargers in 2022. His resilience was further tested in 2025 when he was diagnosed with testicular cancer, yet he continued to play, earning the Ed Block Courage Award.
Beyond his athletic achievements, Singleton is a dedicated advocate for the Special Olympics, a commitment deeply rooted in his relationship with his sister, Ashley, who is a gold-medal-winning Special Olympics athlete. His career is marked by both physical endurance—such as playing through a ruptured ACL in 2024—and a willingness to adapt to changing circumstances. From his early days as an undrafted rookie to his current role as a veteran leader for the Denver Broncos, Singleton’s path demonstrates the impact of persistence and the importance of leveraging every available opportunity to reach the highest levels of professional sport.
