The puck has officially dropped on the PWHL expansion process, with existing teams releasing protected players lists as incoming 2025/26 franchises Seattle and Vancouver begin to build rosters.

The teams' exclusive signing window opened Wednesday morning and runs through Sunday, with the 2025 Expansion Draft set for Monday evening.

Both Seattle and Vancouver can sign up to five players each from the league's unprotected and free agency pool this week.

Regardless of how many athletes the franchises choose to sign, the expansion process requires that the new teams grow their rosters to 12 total players by the end of Monday's draft, before completing their 23-athlete lineups alongside the other six teams during the June 24th PWHL entry draft.

The six founding PWHL clubs could only list three protected players for this week's signing window and next week's expansion draft, forcing some difficult roster decisions.

The Boston Fleet did not opt to add captain Hilary Knight to the protected players list — despite the 35-year-old leading the league in scoring this season — with New York's Alex Carpenter and Toronto's Sarah Nurse also headlining the unprotected list.

With growth front-of-mind, the PWHL Players Association also announced that its members voted late last week to publicly disclose their salaries — a move expected to aid negotiations during this week's signing window.

"This will be a tool for players as they consider opportunities across the league," PWHLPA executive director Malaika Underwood told The Athletic.
