Matt Grzelcyk Bio
Matthew Grzelcyk is an American professional ice hockey player who plays as a defenseman for the Chicago Blackhawks of the National Hockey League (NHL). Born and raised in the Boston area, Grzelcyk was selected by the Boston Bruins with the 85th overall pick in the third round of the 2012 NHL Entry Draft. After spending the first twelve seasons of his professional career in the Bruins organization, he has also suited up for the Pittsburgh Penguins before joining the Blackhawks. Standing 5 feet 10 inches tall and weighing 180 pounds, he is recognized as a steady, puck-moving defenseman who plays the left side.
Early Life and Background
Matthew Grzelcyk was born on January 5, 1994, in Boston, Massachusetts, in the United States. He grew up in Charlestown, where he lived just a block from the local rink at Edwards Playground, and spent much of his childhood playing hockey in the neighborhood. As a youth, Grzelcyk played in the 2007 Quebec International Pee-Wee Hockey Tournament with the Middlesex Islanders minor ice hockey team, lining up alongside future NHL players Jon Gillies and Miles Wood. He also grew up with fellow 2012 NHL Entry Draft pick Jimmy Vesey, and the two first met around the age of six while playing for the Middlesex Islanders.
Grzelcyk attended Belmont Hill School, a well-known preparatory school in the Boston area with a strong hockey tradition. He later joined the United States National Team Development Program in the United States Hockey League, where he developed against top amateur competition. During his time in the program, he won a gold medal at the 2012 Under-18 World Junior Championship in the Czech Republic, an early sign of his international pedigree.
Path to Hockey
After his development in the USNTDP, Grzelcyk committed to play college hockey for Boston University in the Hockey East Conference of the NCAA. In his first season with the Terriers, he was named to the Hockey East All-Freshman team in 2012, signaling a smooth transition to the college ranks. He was selected to the preliminary roster for the 2013 World Juniors but did not make the final cut, while the following year he served as an assistant captain for the United States at the 2014 World Juniors, where the team did not medal.
Grzelcyk served as captain of the Boston University Terriers during both his junior and senior seasons, demonstrating the leadership qualities he had shown since his youth days. One of his signature college moments came in the 63rd Beanpot, when he scored the overtime winning goal to deliver Boston University its 30th title and was named the tournament Most Valuable Player. Across his four-year career at BU, he played 124 games, scoring 26 goals and adding 69 assists, before turning professional.
Matt Grzelcyk Career
Early Career (2016–2017)
On April 1, 2016, Grzelcyk signed a two-year entry-level contract with the Boston Bruins, beginning his professional career ahead of the 2016–17 season. He was first assigned to Boston’s American Hockey League affiliate, the Providence Bruins, on an Amateur Tryout Agreement for the remainder of the 2015–16 campaign to get his footing at the professional level. He made his NHL debut on December 14, 2016, in a 4–3 overtime loss to the Pittsburgh Penguins, marking the start of his top-flight career.
Boston Bruins Breakthrough (2017–2024)
Grzelcyk returned to the NHL on November 22, 2017, after spending roughly six weeks earlier that season with the Providence Bruins. In his first game back, he recorded his first NHL assist on a goal from teammate Jake DeBrusk against the New Jersey Devils. Two days later, on November 24, 2017, he scored his first NHL goal in a 4–3 victory over the Pittsburgh Penguins, the same franchise he had debuted against.
During the summer before the 2018–19 season, Grzelcyk signed a two-year contract to remain with the Bruins. That year, he and the Bruins advanced to the 2019 Stanley Cup Finals, where he suffered a head injury after taking an elbow from St. Louis Blues center Oskar Sundqvist. Sundqvist was suspended for Game 3 of the finals, although the Blues ultimately won the championship in seven games.
After eight seasons in the Boston organization, Grzelcyk departed as a free agent and signed a one-year, $2.75 million contract with the Pittsburgh Penguins on July 1, 2024, joining the team for the 2024–25 campaign.
Chicago Blackhawks Era (2025–Present)
Following his time in Pittsburgh, Grzelcyk went unsigned during the 2025 offseason and joined the Chicago Blackhawks on a professional tryout agreement for the 2025–26 preseason on September 16, 2025. Several weeks later, on October 5, 2025, he signed a one-year contract with Chicago for the 2025–26 season, completing his move to his third NHL organization. The signing marked a fresh start for the veteran defenseman as he looked to contribute to a rebuilding Blackhawks roster.
Playing Style and Strengths
Grzelcyk is known as a mobile, puck-moving defenseman who excels in transition and contributes regularly on the power play. At 5 feet 10 inches, he relies on his skating, hockey sense, and accurate passing rather than physicality to influence games. His left shot and ability to walk the blue line have made him a reliable option for coaches looking to generate offense from the back end.
Notable Events and Milestones
Among the defining moments of Grzelcyk’s career are his Beanpot-winning overtime goal and Most Valuable Player award in 2015, his first NHL goal against the Pittsburgh Penguins in 2017, and his run to the 2019 Stanley Cup Finals with the Boston Bruins. His willingness to take a professional tryout with Chicago in 2025 also underscored his determination to keep playing at the NHL level into his early thirties.
Matt Grzelcyk Personal Life
Family Background and Hockey Lineage
Hockey runs deep in the Grzelcyk family. His father, John Grzelcyk Sr., began working at Boston Garden in 1967 and has remained with the organization ever since, even as the arena was renamed TD Garden. Grzelcyk’s older brother, also named John, has followed his father into the same workplace, and the two elder Grzelcyks are members of the arena’s bull gang, the crew responsible for converting the building between hockey and basketball configurations. John Jr. has also served as a Zamboni driver for certain Bruins games.
Personal Life
On October 25, 2021, Grzelcyk’s father was diagnosed with prostate cancer. Despite undergoing radiation treatments, John Sr. continued working at TD Garden, a testament to the resilience that runs in the family. Beyond his immediate family ties to the Bruins’ home arena, Grzelcyk has maintained long friendships from his Charlestown childhood, including his lifelong bond with Jimmy Vesey, a fellow member of the 2012 draft class.
2025 Season Performance
Grzelcyk’s 2025 calendar began with his release from the Pittsburgh Penguins after the 2024–25 campaign, leaving him without a contract heading into training camp. On September 16, 2025, he joined the Chicago Blackhawks on a professional tryout agreement for the 2025–26 preseason, using the opportunity to show that he could still contribute at the NHL level. His strong showing during the preseason earned him a one-year contract signed on October 5, 2025, locking in his spot on the Blackhawks’ blue line.
Now 31 years old, Grzelcyk is expected to serve as a veteran presence on a young Chicago defensive corps during the 2025–26 season. His puck-moving skill set and left shot fit the modern style the Blackhawks are building around as they continue their rebuild. With his NHL career now extending into a 13th professional season, Grzelcyk enters the year aiming to deliver steady two-way play and help mentor the team’s emerging defensemen.
