Vanecek will not be in the lineup for Friday's preseason clash with the Rangers, Stefen Rosner of NHL.com reports.
Despite earlier reports indicating that Vanecek would start Friday, it seems the Islanders will utilize Semyon Varlamov in the crease while Joshua Kotai serves as the No. 2 option. Barring any setbacks, it seems likely that Varlamov will take the backup role to open the season, which would leave Vanecek headed for waivers or the minors.
