Early Life and Background
Mark Glowinski II was born on May 3, 1992, in Wilkes-Barre, Pennsylvania, and was raised as one of two children to Dawn Glowinski and Mark Glowinski Sr. He grew up in the same northeastern Pennsylvania community where he would later return to give back to local athletes. His upbringing in Wilkes-Barre placed him close to a tight-knit football culture that helped shape his early interest in the sport.
Glowinski attended G.A.R. Memorial High School in Wilkes-Barre, where he played as a 6-foot-4, 275-pound offensive and defensive lineman for the Grenadiers football team. He was a three-year starter on both sides of the ball and served as a team captain. He also earned a place on the Garrett Ford Academic Honor Roll, demonstrating a balance between athletics and academics. Outside of football, he competed in track and field, participating in shot put, discus, and javelin events.
Path to American Football
After high school, Glowinski took the junior college route and joined Lackawanna College, where he played as a starting offensive lineman for the Lackawanna Falcons during the 2010 and 2011 seasons. His performance at that level earned him a spot on the 2011 NJCAA second-team All-American list. Rated as a three-star recruiting prospect, he drew scholarship offers from West Virginia, Connecticut, and Kansas State.
Glowinski transferred to West Virginia University for the 2012 season, where he sat out as a junior redshirt before stepping in as a starting right guard for all 12 games of the 2013 season. Although originally projected as a tackle, he settled in at guard and became a reliable presence on the Mountaineers offensive line. At West Virginia he majored in multidisciplinary studies. After the 2014 season he declared for the 2015 NFL Draft, where the Seattle Seahawks selected him in the fourth round.
Mark Glowinski Career
Early Career (2015-2016)
Glowinski began his NFL career with the Seattle Seahawks after being drafted 134th overall in 2015. He spent his rookie season developing behind veterans and adjusting to the speed of the professional game. The following year, in 2016, he broke into the starting lineup and earned the starting left guard position, starting all 16 games for the Seahawks.
His strong 2016 campaign established him as a long-term starter and gave him valuable experience within a winning organization. That foundation set the stage for the first major move of his career when he was claimed off waivers by the Indianapolis Colts in December 2017.
Seattle Seahawks Breakthrough (2015-2017)
With the Seattle Seahawks, Glowinski transitioned from developmental rookie to full-time starter. After appearing in a reserve role in 2015, he secured the starting left guard job in 2016 and held it for a full season. The experience of starting every game for one of the NFL’s most consistent franchises helped him refine his pass protection and run blocking technique.
Heading into 2017, Glowinski shifted to right guard and started the first two games before slipping down the depth chart. After injuries and the emergence of other linemen pushed him to fourth on the depth chart, the Seahawks waived him on December 16, 2017. The move opened the door for his next opportunity in Indianapolis.
Indianapolis Colts First Stint (2017-2021)
Glowinski was claimed off waivers by the Indianapolis Colts on December 18, 2017, quickly finding a new home on the offensive line. He began his Colts tenure as a backup before taking over as the starting right guard in Week 6 following a season-ending injury to Matt Slauson. He went on to start nine of the final 11 games that season, cementing his role as a starter.
On January 29, 2019, the Colts rewarded his steady play with a three-year, $18 million contract extension that ran through the 2021 season. Across his first stint in Indianapolis, Glowinski became a dependable interior presence and one of the most consistent linemen on the roster, helping protect the quarterback and open lanes in the running game.
New York Giants Era (2022-2023)
On March 17, 2022, Glowinski signed a three-year, $20 million contract with the New York Giants. He stepped into a starting role and brought veteran experience to a young offensive line. His time in New York offered him the chance to play in a different offensive system alongside new teammates.
The 2023 season proved more difficult. After a rough performance in Week 1 against the Dallas Cowboys, Glowinski was benched in favor of Marcus McKethan for the Week 2 matchup against the Arizona Cardinals. The Giants released him on March 4, 2024, ending his stint with the team after two seasons.
Indianapolis Colts Second Stint (2024-Present)
After working his way back into football shape, Glowinski returned to familiar territory when he was signed to the Indianapolis Colts practice squad on November 21, 2024. He started the next three games, demonstrating that he still had starting-caliber ability. On December 24, 2024, the Colts signed him to the active roster, where he resumed a starting guard role for the remainder of the season.
