The 25-year-old defenseman was placed on NHL waivers by the Pittsburgh Penguins on Saturday after failing to make the rebuilding squad's team out of camp. Alexeyev signed a one-year deal with the Penguins in July after the Capitals declined to extend him a qualifying offer. Per the Penguins, Alexeyev was one of 10 cuts on Saturday, which saw four players assigned to the Wilkes-Barre/Scranton Penguins, five placed on waivers, and another released from their PTO.
