Isaac Alarcon Bio
Isaac Alarcón García (born July 27, 1998) is a Mexican professional American football offensive tackle for the San Francisco 49ers of the National Football League (NFL). Standing 6 feet 7 inches tall and listed at 145 kilograms, he is one of the most prominent Mexican-born linemen to reach the league through the International Player Pathway Program. He previously spent three seasons with the Dallas Cowboys organization after signing in 2020.
Early Life and Background
Alarcón was born in Monterrey, Nuevo León, Mexico, a city with a strong football culture that helped shape his early athletic development. He first started playing football at age 14 at Club Pumas, a local youth football club, where coaches introduced him to the fundamentals of the offensive line. He later attended UANL High School No. 9 in Monterrey, continuing to play the sport while balancing his studies.
After high school, Alarcón accepted a football scholarship from the Monterrey Institute of Technology and Higher Education (ITESM), one of the most respected private universities in Mexico. At ITESM, he played both right and left tackle, refining the technique and size that would later catch the attention of NFL scouts. His college career was capped in 2019 when he helped ITESM win the Mexican college football national championship, earning CONADEIP All-Star recognition in the process.
Path to American Football
Alarcón’s international credentials grew in 2016 when he represented Mexico at the U19 World Championship in China, helping the national team earn a bronze medal. The experience competing against top teenage talent from across the globe strengthened his resolve to pursue football at the highest possible level.
His breakthrough into the American game came in October 2019, when he was selected from an international combine held in Germany. Following the combine, he spent two months training alongside NFL players and draft hopefuls at the IMG Academy in Florida, gaining exposure to professional coaching, strength programs, and the speed of the North American game. That preparation set the stage for his entry into the NFL through the league’s International Player Pathway Program.

Early Career (2020)
On April 27, 2020, Alarcón was allocated to the Dallas Cowboys as part of the International Player Pathway Program, becoming one of the first Mexican-born players to join the storied franchise through the initiative. His initial stint with Dallas was brief at the top of the roster, as he was waived on September 5, 2020, and immediately signed to the team’s practice squad the following day.
Despite spending his rookie year on the practice squad, Alarcón used the season to absorb professional schemes, build his body, and adjust to the pace of NFL practices. On January 4, 2021, the Cowboys rewarded his development with a reserve/future contract, signaling that the organization viewed him as a long-term developmental project.
Dallas Cowboys Development (2021–2023)
Alarcón’s tenure with Dallas featured repeated practice-squad stints. On August 31, 2021, he was waived and re-signed to the practice squad the next day. He also received selection news from north of the border, as the Calgary Stampeders picked him in the third round of the 2021 CFL Global Draft on April 15, 2021, with his roster exemption kept for the 2021 season.
He signed another reserve/future contract on January 18, 2022, and continued his pattern of late-summer movement when he was waived on August 30, 2022, and returned to the practice squad the following day. On January 26, 2023, he signed yet another reserve/future deal with the Cowboys, but his role reportedly changed that year as the organization began exploring him as a defensive tackle in addition to his offensive tackle background. He was waived as part of final roster cuts on August 29, 2023, closing his Cowboys chapter after three seasons of practice-squad service.
San Francisco 49ers Era (2024–Present)
On January 23, 2024, Alarcón signed a reserve/future contract with the San Francisco 49ers, beginning a new chapter in the Bay Area. He was waived on August 27, 2024, and re-signed to the practice squad, continuing the developmental arc that has defined his professional journey.
Alarcón signed a fresh reserve/future contract with San Francisco on January 7, 2025, securing his place in the organization. On April 16, 2025, he was suspended for six games for violating the NFL’s performance-enhancing substances policy. He was waived on October 13, 2025, and re-signed to the practice squad the next day, keeping him within the 49ers system as the season progressed.
Driving Style and Strengths
At 6 feet 7 inches tall and 145 kilograms, Alarcón brings the kind of size and length NFL teams covet at the tackle position. His background as a dual-threat offensive and defensive lineman at ITESM has given him positional flexibility, and his International Player Pathway experience reflects strong work ethic, coachability, and a willingness to embrace multiple roles along the line of scrimmage.
Notable Events and Milestones
Alarcón’s most significant milestone remains his 2019 contribution to ITESM’s Mexican college football national championship and his CONADEIP All-Star selection. His entry into the NFL as a Mexican-born offensive tackle through the International Player Pathway Program also stands as a career-defining moment, marking him as a trailblazer for football players from his country.
