The 2026 NHL trade deadline has sent MacKenzie Weegar from the Calgary Flames to the Utah Mammoth, a move that significantly impacts fantasy hockey lineups. The 32-year-old defenseman, despite a down season by his standards, joins a playoff-contending team and is expected to slot into Utah's top defensive pairing alongside Mikhail Sergachev.

While Weegar's special teams opportunities may decrease slightly, his overall production should improve with the Mammoth's superior offensive capabilities. The Flames rank dead-last in goals per game at 2.45, while Utah offers a more favorable environment for offensive contributions. However, work visa issues could sideline Weegar for 4-10 days, creating a dilemma for fantasy managers with postseason rosters due soon.

In Calgary, rookie Zayne Parekh stands to benefit most from Weegar's departure, inheriting top power-play duties and increased ice time. The 20-year-old could emerge as a deep-league sleeper as the Flames shift focus to developing young talent for the future. This trade deadline reshuffling highlights the importance of monitoring visa situations and prospect opportunities in fantasy hockey strategy.
