Johnathan Kovacevic Bio
Johnathan Kovacevic (born July 12, 1997) is a Canadian professional ice hockey player who serves as a defenceman for the New Jersey Devils of the National Hockey League (NHL). Standing 6 feet 5 inches tall and weighing roughly 224 pounds, he uses his size and mobility to handle difficult matchups at even strength and on the penalty kill. Selected in the third round, 74th overall, by the Winnipeg Jets in the 2017 NHL Entry Draft, Kovacevic has built his career through steady development in both college and the American Hockey League (AHL) before establishing himself as a steady NHL defenceman.
A native of Hamilton, Ontario, Kovacevic is also a college graduate who balanced academics with athletics. His route from the Merrimack College Warriors to a multi-year contract with the New Jersey Devils reflects a patient climb through professional hockey’s developmental ranks.
Early Life and Background
Johnathan Kovacevic was born on July 12, 1997, in Hamilton, Ontario, Canada. He grew up in a household shaped by his parents’ background as immigrants from the former Yugoslavia. His father, Novica, is from Nikšić, Montenegro, while his mother, Angie, is from Bosnia and Herzegovina. The family maintained ties to their Balkan heritage while settling into life in southern Ontario.
Hamilton has long been a strong hockey community, and Kovacevic developed his game there before moving on to junior and collegiate opportunities. His combination of height, reach, and a right-handed shot made him a natural fit for the defenceman position. By the time he reached his draft year, his blend of size and skating ability had attracted attention from NHL scouts.
Path to Hockey
Kovacevic joined the Merrimack College Warriors beginning with the 2016–17 season. During his freshman year, he appeared in 36 games and tallied 19 points, earning Merrimack’s rookie of the year honor and a place on the Hockey East All-Academic Team. The early success set the foundation for his development as a two-way defenceman at the collegiate level.
In his sophomore season, Kovacevic played 34 games and recorded 17 points while again being recognized on the Hockey East All-Academic Team. Prior to his final campaign, he was named an alternate captain and contributed four goals in 31 appearances, while also being recognized as team MVP. Across 101 games with Merrimack, he produced nine goals and 45 assists, demonstrating his ability to contribute offensively from the back end while also managing defensive responsibilities.
Kovacevic was selected by the Winnipeg Jets in the third round, 74th overall, of the 2017 NHL Entry Draft. Rather than turn professional immediately, he continued his development at Merrimack and earned a civil engineering degree alongside his hockey responsibilities, completing his studies as his draft rights remained with the Jets.
Johnathan Kovacevic Career
Early Career (2019–2022)
After leaving Merrimack, Kovacevic signed a two-year entry-level contract with the Winnipeg Jets on March 17, 2019. He made his professional debut with the Jets’ AHL affiliate, the Manitoba Moose, on April 14, 2019, scoring one goal and adding an assist against the Chicago Wolves. The brief appearance offered an early glimpse of his offensive instincts from the blue line.
On August 13, 2021, the Jets re-signed Kovacevic to a one-year, two-way contract worth $750,000 at the NHL level. In the following 2021–22 season, he was recalled from the Moose and played in his first NHL game with the Jets on January 28, 2022 against the Vancouver Canucks, logging 10:21 of ice time and registering one shot on goal. As a restricted free agent, he was later re-signed to a three-year contract extension with Winnipeg on July 22, 2022, signaling the organization’s continued belief in his projectable role at the NHL level.
Winnipeg Jets Era (2019–2022)
Although Kovacevic’s NHL opportunities with the Jets were limited to a single appearance, his time within Winnipeg’s organization provided important professional seasoning. He spent the bulk of his first three pro seasons with the Manitoba Moose, refining his defensive game, adjusting to the pace of professional hockey, and preparing for an NHL opportunity. The Jets’ depth on the right side of the defence, however, kept him in the AHL longer than he had hoped.
Montreal Canadiens Era (2022–2024)
After attending the Jets’ 2022 training camp in preparation for the 2022–23 season, Kovacevic was placed on waivers during the pre-season and was claimed the following day by the Montreal Canadiens on October 8, 2022. Acquired to address weakness on the right side of the Canadiens’ defence, he made his debut in the season opener versus the Toronto Maple Leafs on October 12 and immediately became a regular part of the lineup, surpassing his prior NHL appearance total within eight days. He was regularly paired with rookie defenceman Jordan Harris and drew praise from Montreal’s coaching staff for his calm play and reliability.
On November 14, 2022, Canadiens executive Jeff Gorton advised Kovacevic to find regular accommodations in Montreal, an indication that the organization viewed him as a long-term fixture. Kovacevic later reflected that the gesture suggested the team liked what they saw and wanted him for a longer run. On December 6, 2022, he scored his first career NHL goal in a 4–2 road victory against the Seattle Kraken, cementing his arrival as an NHL contributor.
New Jersey Devils Era (2024–Present)
Prior to the NHL free agency period, Kovacevic was traded to the New Jersey Devils on June 30, 2024 in exchange for a fourth-round selection in the 2026 NHL Entry Draft. The move placed him on a young, fast Devils roster that valued his right-handed shot, defensive awareness, and penalty-killing ability. He quickly integrated into the lineup and became a steady presence on the back end.
On March 7, 2025, Kovacevic agreed to a five-year, $20 million contract extension with the Devils, locking in his future with the franchise through the end of the decade. The deal reflected both his growth as a player and the organization’s confidence in his long-term fit within their defensive group.
Playing Style and Strengths
Kovacevic is recognized for his size, mobility, and composure under pressure. His right-handed shot and strong skating make him effective on the penalty kill and in shutdown matchups against top opposition forwards. Throughout his time in Montreal and New Jersey, he has been praised for his willingness to block shots, his reliable first pass out of the defensive zone, and his steady improvement in offensive-zone reads.
Notable Events and Milestones
Among his signature moments, Kovacevic’s first NHL goal against the Seattle Kraken on December 6, 2022, stands out as the breakthrough that confirmed his place at the top level. His trade to the New Jersey Devils and subsequent five-year contract extension underscored how far he had progressed from a third-round draft pick to a trusted everyday NHL defenceman.
