Early Professional Career (2019-2022)
After being drafted by the Winnipeg Jets in 2017, Kovacevic continued his development at Merrimack before signing his first professional contract. He signed a two-year entry-level contract with the Jets on March 17, 2019, officially beginning his professional hockey journey. Kovacevic made his professional debut with the Jets’ American Hockey League (AHL) affiliate, the Manitoba Moose, on April 14, 2019. In that debut against the Chicago Wolves, he scored one goal and registered an assist, signaling his potential as an offensive defenceman at the professional level.
Following his first professional season, Kovacevic continued with the Moose organization. On August 13, 2021, the Jets re-signed him to a one-year, two-way contract worth $750,000 at the NHL level. This contract represented a vote of confidence in his development and positioned him for an opportunity at the NHL roster. The 2021-22 season would prove to be his breakthrough year at the highest level.
NHL Breakthrough with Winnipeg Jets (2022)
During the 2021-22 season, Kovacevic received his first NHL recall from the Moose and made his NHL debut with the Jets on January 28, 2022, against the Vancouver Canucks.

As a restricted free agent following that season, Kovacevic re-signed to a three-year contract extension with the Jets on July 22, 2022. This deal represented job security and an opportunity to compete for a regular role during training camp. However, his time in Winnipeg was about to take an unexpected turn.
Montreal Canadiens Tenure (2022-2024)
After attending the Jets’ 2022 training camp, Kovacevic was placed on waivers during the pre-season. He was claimed by the Montreal Canadiens on October 8, 2022. Acquired to help address weakness on the right side of the Canadiens’ defence, Kovacevic made his debut in the season opener versus the Toronto Maple Leafs on October 12. He immediately became a regular part of the lineup and surpassed his prior NHL appearance total within eight days of his first game.
Kovacevic was regularly paired with rookie defenceman Jordan Harris and drew praise from the coaching staff for his steady play. On November 14, Canadiens executive Jeff Gorton advised Kovacevic to find regular accommodations in Montreal, signaling that he had earned a permanent roster berth. Kovacevic responded by saying it gave him confidence that the organization valued his contributions. A major milestone came on December 6, 2022, when he scored his first career NHL goal in a 4-2 road victory against the Seattle Kraken.

This move positioned Kovacevic with a franchise that has invested heavily in building a competitive roster.
On March 7, 2025, Kovacevic agreed to a five-year, $20 million contract extension with the Devils.
