Yesterday Kate Cimini from Today's Slap Shot wrote a great piece about the NWHL's practice players. Each club in the NWHL carries four practice players who are considered "non-contract" players according to commissioner Dani Rylan. For all intents and purposes, the four women skating with the Riveters serve as the club's farm team. To get a better idea of what role these women will serve for the clubs they are attached to, here's Kate Cimini's take on practice players.
If and when rostered players are unable to make a game or six, a practice player can step in, and possibly earn herself a spot on the roster come next season.
