The Chicago Blackhawks and general manager Stan Bowman made a couple of roster announcements on Thursday. 

After saying he had an announcement to make regarding defenseman Brent Seabrook yesterday, Bowman followed that up on Thursday. 

Seabrook is among three players placed on injured reserve. 

Centers Jonathan Toews and Kirby Dach were placed on long term injured reserve. 

While Dach is likely gone for the season, plenty of question marks still surround Toews and all we know now is that he'll miss at least 10 games.
