Born on May 3, 1992, in Wilkes-Barre, Pennsylvania, he developed into a durable interior lineman through junior college and a major conference program before being drafted by the Seattle Seahawks. Across his career, Glowinski has appeared for the Seattle Seahawks, Indianapolis Colts, and New York Giants, earning starting roles at both guard spots.
Standing 6 feet 4 inches tall and playing around 315 pounds, Glowinski is recognized for his positional versatility, his run-blocking strength, and his steady presence along the offensive line. His professional journey includes a Super Bowl appearance, multi-year starting duties, and a return to Indianapolis late in the 2024 season.
Early Life and Background
Mark Glowinski II was born on May 3, 1992, in Wilkes-Barre, Pennsylvania, the son of Mark Glowinski Sr. and Dawn Glowinski. He grew up in the same northeastern Pennsylvania city where he would later return to host youth football camps. As a young athlete, he gravitated toward contact sports and showed early promise in both football and throwing events.
Glowinski attended G.A.R. Memorial High School in Wilkes-Barre, where he lined up as an offensive and defensive lineman for the Grenadiers football team. He became a three-year starter on both sides of the ball and eventually served as team captain, while also earning recognition on the Garrett Ford Academic Honor Roll. During his prep years, he also competed in track and field, participating in shot put, discus, and javelin events that helped develop his overall athleticism.
Path to the NFL
After high school, Glowinski first played at Lackawanna College, where he joined the Lackawanna Falcons as a starting offensive lineman from 2010 through 2012. His play at the junior college level was strong enough to earn a 2011 NJCAA second-team All-American selection, marking him as one of the top community college linemen in the country.
Rated as a three-star recruiting prospect, Glowinski received scholarship offers from West Virginia, Connecticut, and Kansas State. He ultimately chose West Virginia University, where he majored in multidisciplinary studies. He transitioned from tackle to right guard and started all 12 games during the 2013 season, then sat out the 2014 campaign as a redshirt senior. In 2014, he was named first-team All-Big 12, cementing his status as an NFL prospect.
Mark Glowinski Career
Early Career (2015-2017)
Glowinski was selected by the Seattle Seahawks in the fourth round, 134th overall, of the 2015 NFL Draft. He spent his rookie season developing behind established veterans before breaking into the lineup the following year. In 2016, he claimed the starting left guard job and started all 16 regular season games, showcasing the durability and technique that had defined his college career.
Glowinski entered the 2017 season as Seattle’s starting right guard but started only the first two games before losing the job to Oday Aboushi. As rookie Ethan Pocic emerged and injuries shuffled the depth chart, Glowinski slipped to fourth on the guard depth chart and was waived by the Seahawks on December 16, 2017.
Indianapolis Colts Breakthrough (2017-2021)
On December 18, 2017, Glowinski was claimed off waivers by the Indianapolis Colts, giving him an immediate opportunity to compete for a roster spot. He began the 2018 season as a backup before being named the starting right guard in Week 6 after Matt Slauson suffered a season-ending injury. Glowinski responded by starting nine of the Colts’ final 11 games and locking down the position.
On January 29, 2019, Glowinski signed a three-year, $18 million contract extension that kept him in Indianapolis through the 2021 season. He became a mainstay on the Colts’ offensive line, contributing to the team’s ground game with his combination of size, strength, and positional awareness. His reliability made him one of the more consistent guards in the AFC South during this period.
New York Giants Era (2022-2023)
On March 17, 2022, Glowinski signed a three-year contract worth $20 million with the New York Giants, signaling a major free-agent investment in his services. He slotted in as a starting guard and provided veteran leadership along an offensive line that was being retooled around a young quarterback.
Glowinski’s time in New York was shortened by performance struggles, and he was benched after a difficult Week 1 showing against the Dallas Cowboys in September 2023, with Marcus McKethan taking over as the starting right guard the following week. The Giants released him on March 4, 2024, ending his second multi-year deal in as many stops.
Indianapolis Colts Second Stint (2024-Present)
On November 21, 2024, Glowinski was signed to the Indianapolis Colts practice squad, returning to a familiar franchise. After starting the next three games, he was promoted to the active roster on December 24, 2024, providing experienced depth at guard during the late-season push.
Driving Style and Strengths
Glowinski is regarded as a physical, run-first guard whose size and strength allow him to move defensive tackles off the ball. He has shown positional flexibility by starting at both left and right guard, and his track and field background contributes to his explosiveness in short areas.
Notable Events and Milestones
Highlights of Glowinski’s career include a 2011 NJCAA second-team All-American selection, first-team All-Big 12 honors in 2014, starting all 16 games for Seattle in 2016, and earning a multi-year extension with Indianapolis in 2019. His return to the Colts in 2024 also marked a homecoming of sorts for the Pennsylvania native.

His standout seasons with the Indianapolis Colts and his starting duties with the Seattle Seahawks and New York Giants underscore a career built on consistency in the trenches.
NFL Highlights
Glowinski’s most notable NFL stretch came during his first stint with the Indianapolis Colts, where he transitioned from a waiver pickup into a multi-year starter. He started all 16 games for the Seattle Seahawks in 2016, played key games for the Colts across several seasons, and returned to Indianapolis late in 2024 to add veteran presence on the offensive line.
Other Performances

Mark Glowinski Family
Family Background and Racing Lineage
Glowinski was raised in Wilkes-Barre, Pennsylvania, by his father, Mark Glowinski Sr., and his mother, Dawn Glowinski. He grew up as one of two children in a family rooted in the same northeastern Pennsylvania community he continues to support today.
Personal Life
Outside of football, Glowinski enjoys competitive bowling and remains connected to his hometown of Wilkes-Barre. On July 16, 2022, he coached his first high school football camp at the King’s College Athletic Complex in Wilkes-Barre, giving back to the same region where he first learned the game.
2025 Season Performance
Looking ahead to the 2025 season, Glowinski is expected to compete for a depth role along the Indianapolis Colts’ offensive line after rejoining the team late in 2024. His late-season starts before being elevated to the active roster suggest that he remains a trusted option for the coaching staff.
Under his current contract running through 2026, Glowinski provides experienced insurance at both guard spots while mentoring younger linemen. His familiarity with the Colts’ offensive scheme from his first stint should help him integrate quickly during offseason workouts and training camp.
Should he secure a starting job, Glowinski would offer the Colts a power-based blocker in the run game and a steady pass protector. Even in a reserve capacity, his durability and positional flexibility give Indianapolis a reliable veteran presence heading into the new season.
