Scherbak, who was placed on waivers by the Montreal Canadiens in early December, has just one point in eight NHL games this season. The 23-year-old was a first-round pick in 2014.
Wideman, who’s played just one game with the Panthers, was part of a trade that sent Alex Petrovic to the Edmonton Oilers in exchange for the defenceman and a 2019 third-round pick on Dec. 30. Wideman started the year with the Ottawa Senators, and has two goals and seven points in 25 games this season.
A first-round pick with St. Louis in 2012, Schmaltz was a healthy scratch for nine straight games – and 19 of 39 games this season – before hitting the waiver wire. The 25-year-old has only two assists in 20 games with the Blues this season and five points in 42 NHL games overall.
