The Chicago Blackhawks have agreed to a six-year contract with defenseman Alex Vlasic, rewarding one of their best young players with a long-term deal.

The team announced the move Thursday. The contract runs through the 2029-30 season with a $4.6 million salary cap hit.

The Chicago Blackhawks have agreed to a three-year contract with Frank Nazar, one of the team's top prospects.

The Blackhawks announced the deal on Saturday, two days after Nazar and Michigan lost 4-0 to Boston College in the Frozen Four. The entry-level agreement runs through the 2025-26 season at a $950,000 salary-cap hit.

Noah Hanifin and the Vegas Golden Knights have agreed to an eight-year contract extension worth $7.35 million annually, the team announced Thursday.

Re-signing Hanifin, who was set to become a pending unrestricted free agent at the end of the season, to a long-term deal comes a little more than a month after the defending Stanley Cup champion Golden Knights acquired the 27-year-old defenseman in a three-team trade with the Calgary Flames and the Philadelphia Flyers just days before the NHL trade deadline.
