Player StatusMegan Gustafson out for July 16, 2026 game (personal reasons) [^][^][^]
Portland Fire Record10-14 [^]
Washington Mystics Record12-10 [^]
Portland Fire center Megan Gustafson will miss a key July 16 game. Megan Gustafson, a critical rotation player for the Portland Fire, is confirmed to miss the July 16, 2026, game against the Washington Mystics due to personal reasons [^][^][^]. Gustafson is highly valued for her efficient post scoring, her ability to space the floor as a perimeter threat, and her role as a primary finisher in pick-and-roll sets [^][^].

This situation is expected to impact the team's offensive execution. Gustafson's absence is also projected to affect the team's overall performance, especially as the Portland Fire entered this game with a 10-14 record [^][^][^].
