Overview

• The Stars shipped 30-year-old defenseman Matt Dumba and their 2028 second-round pick to Pittsburgh in exchange for 24-year-old Vladislav Kolyachonok, with no salary retention on either side.
• Dallas will remove $2.975 million from its $3.75 million cap hit for the 2025-26 season, pulling the team back under the NHL salary cap ceiling.
• Dumba, who recorded one goal and nine assists in 63 games last season, enters the final year of his two-year, $7.5 million deal and will compete for a bottom-pairing role in Pittsburgh’s crowded blue-line corps.
• Kolyachonok joins the Stars with one year remaining on his two-year, $1.55 million contract and will seek an expanded NHL role after averaging 13:01 of ice time over 35 appearances last season.
• Pittsburgh’s acquisition of a veteran defenseman and a future draft pick underscores its rebuild strategy of blending present-day depth with long-term asset accumulation.
