Dano, 20, is on an entry-level contract and had 21 points (eight goals) in 35 games for Columbus in his first NHL season. He had 19 points (11 goals) in 39 games for the Springfield Falcons of the AHL in 2014-15. The Hawks acquired him during the summer as part of the Brandon Saad trade. He was expected to make the team but will head to Rockford for extra seasoning.
Forwards Ryan Hartman, Vincent Hinostroza, Brandon Mashinter, Dennis Rasmussen and Garret Ross and defensemen Erik Gustafsson and Ville Pokka were also sent to Rockford.
Dano has played in the Kontinental Hockey League and has represented Slovakia at the IIHF's World Championship (2013 and 2015) and World Junior Championship (2012-14). The Blue Jackets selected him with their third first-round pick (No. 27) in the 2013 draft.
The team’s active roster now includes 13 forwards, nine defensemen and three goaltenders.
