Isaac Seumalo Bio
Isaac Seumalo (born October 29, 1993) is an American professional football guard for the Pittsburgh Steelers of the National Football League (NFL). Standing 6 feet 4 inches tall and weighing around 300 pounds, Seumalo has built a reputation as a reliable interior lineman known for his technique and durability. He played college football for the Oregon State Beavers before being selected by the Philadelphia Eagles in the 2016 NFL Draft.
Over the course of his career, Seumalo has earned recognition as a Super Bowl champion and a Pro Bowl selection. After spending his first seven NFL seasons with the Philadelphia Eagles, he joined the Pittsburgh Steelers in 2023 and quickly became a fixture on their offensive line. His journey from a true freshman starter in college to a key veteran guard in the league reflects steady development and consistent performance at every level.
Early Life and Background
Isaac Seumalo was born on October 29, 1993, in Honolulu, Hawaii. He is of Samoan descent, a heritage that connects him to a long Pacific Islander tradition in American football. During his early childhood, Seumalo and his family moved to Corvallis, Oregon, where he would spend the rest of his formative years and first develop his love for the sport.
Seumalo attended Santiam Christian School for his freshman and sophomore years before transferring to Corvallis High School. At Corvallis, he emerged as a two-way lineman, earning 5A First-team All-State honors on both the offensive and defensive lines during his junior and senior seasons. His size, footwork, and football IQ made him one of the most sought-after high school linemen in the Pacific Northwest.
Regarded as a four-star recruit by Rivals.com, Seumalo was listed as the number 3 offensive guard prospect in his recruiting class. He received scholarship offers from several elite programs, including Oregon, Stanford, and Southern California. He ultimately chose Oregon State, where his father Joe Seumalo worked as the defensive line coach, allowing him to play close to home while learning under a familiar voice on the coaching staff.
Path to Professional Football
Seumalo arrived at Oregon State with high expectations and met them almost immediately. In his first season with the Beavers, he became the first true freshman to start at center since Roger Levasa in 1978. He appeared in all 13 games that year, earning Freshman All-American honors from College Football News and CBSSports.com, along with honorable mention All-Pac-12 recognition. His standout performance against Utah, where he helped neutralize reigning Pac-12 Defensive Lineman of the Year Star Lotulelei, gave an early glimpse of his NFL potential.
As a sophomore, Seumalo started 12 of 13 games, splitting time between center and right tackle after missing one game with a knee injury. He earned second-team All-Pac-12 honors and Pac-12 All-Academic first-team recognition. A foot injury in the Hawaii Bowl forced him to redshirt the following season, but he returned as a redshirt junior to start all 12 games at right guard and left tackle. Following that campaign, Seumalo announced his decision to forgo his senior season and enter the NFL Draft, becoming only the sixth Oregon State player in program history to leave early for the league.
Isaac Seumalo Career
Early Career (2016–2017)
On April 29, 2016, the Philadelphia Eagles selected Isaac Seumalo in the third round, 79th overall, of the 2016 NFL Draft. As a rookie, he appeared in limited duty while adjusting to the speed and complexity of the professional game. In 2017, Seumalo played in 14 games and earned the starting left guard role, though a difficult performance in a Week 2 loss to the Kansas City Chiefs led to a brief benching in favor of veteran Stefan Wisniewski.
Despite the midseason setback, Seumalo finished the year strong and was part of the Eagles roster that defeated the New England Patriots 41–33 in Super Bowl LII, earning him his first championship ring. The experience of contributing to a title-winning team as a young lineman proved invaluable for his development.
Philadelphia Eagles Breakthrough (2018–2022)
Seumalo entered the 2018 season as the backup left guard behind Stefen Wisniewski but was named the starter in Week 5. He started the next nine games before a pectoral injury sidelined him for the final three weeks of the regular season. He made another postseason appearance with the Eagles that year, recording a win over the Chicago Bears before a loss to the New Orleans Saints in the divisional round.
On March 4, 2019, Seumalo signed a three-year contract extension with the Eagles through the 2022 season. That year, he appeared in all 17 regular-season games as Philadelphia finished 9–7 and clinched a playoff berth. He played in the team’s lone postseason contest, a loss to the Seattle Seahawks. In September 2020, a knee injury landed him on injured reserve, and he was activated in November, finishing the season with nine appearances.
Injuries continued to test him in 2021 when a Lisfranc injury suffered in Week 3 ended his season after only three games. Seumalo bounced back in 2022, appearing in all 17 regular-season games for just the second time in his career and adding three postseason starts. He helped Philadelphia reach Super Bowl LVII, though the Eagles fell 38–35 to the Kansas City Chiefs. Following the Super Bowl loss, the Eagles chose not to re-sign him, making him a free agent.
Pittsburgh Steelers Era (2023–Present)
On March 18, 2023, Seumalo signed a three-year, $24 million contract with the Pittsburgh Steelers, bringing veteran stability to their offensive line. In his first season in Pittsburgh, he started all 17 regular-season games and earned an overall Pro Football Focus grade of 71.9, ranking 14th among the top 20 highest-graded offensive guards in the league. He allowed 26 pressures and committed only one penalty all year while helping the Steelers reach the postseason, where they lost 31–17 to the Buffalo Bills in the AFC Wild Card round.
During the 2024 preseason, Seumalo suffered a pectoral injury that kept him out of the first four weeks of the regular season. He returned to the starting lineup during Pittsburgh’s Week 5 primetime loss to the Dallas Cowboys. Though he was active for only four games by the team’s Week 9 bye, he took 96.25 percent of offensive snaps and did not allow a single quarterback hit or sack during that stretch. His pass-blocking grade of 74.7 placed him 21st out of 69 eligible offensive guards according to PFF, reinforcing his value as one of the league’s dependable interior protectors.
Driving Style and Strengths
While football linemen are not typically described as drivers, Seumalo’s craft is rooted in leverage, balance, and quick-twitch athleticism. He excels in pass protection thanks to his ability to mirror rushers and recover with sound footwork. His intelligence and communication skills make him a trusted communicator along the offensive front, and his discipline is reflected in his low penalty totals.
Notable Events and Milestones
Seumalo’s most defining moment came as a member of the Philadelphia Eagles’ Super Bowl LII championship team in February 2018. He added a second Super Bowl appearance with the Eagles after the 2022 season. In 2024, Seumalo earned his first career Pro Bowl selection, cementing his status among the league’s top guards.

Isaac’s sister, Jessi Seumalo, works in college athletics as the director of on-campus recruiting for the Washington State football team, continuing the family’s involvement in the sport at multiple levels.

2025 Season Performance
Looking ahead to the 2025 season, Seumalo is expected to remain a central figure on the Pittsburgh Steelers’ offensive line as he enters the third and final year of his contract. After a strong 2024 campaign that ended with his first Pro Bowl nod, he is firmly established as one of the team’s starting guards and a leader in the locker room.
The Steelers will rely on his consistency in both pass protection and run blocking as they look to build on consecutive playoff appearances. With health on his side after a limited regular-season workload in 2024, Seumalo is expected to play a full 17-game slate and continue serving as a steadying presence up front.
Beyond his on-field role, Seumalo’s veteran experience and communication skills are expected to benefit younger linemen on the roster. As Pittsburgh pushes deeper into the AFC playoff picture, his performance will remain a key factor in the team’s pursuit of a championship run.
