The Blackhawks assigned forwards Andreas Martinsen and Dylan Sikura to the AHL on Saturday morning.
Sikura had no goals and three assists in 11 NHL games since being called up to the NHL in December. When he was called up, Sikura led the Rockford IceHogs with nine goals and 18 points in 26 AHL games.
Sikura had three assists in five NHL games last season after signing his entry-level contract following his 54-point (22 goals, 32 assists) senior season at Northeastern University. The Blackhawks drafted him in the sixth round of the 2014 NHL draft.
