The Blackhawks transferred Drake Caggiula to long-term injured reverse, retroactive to Nov. 10, on Wednesday. Chicago also recalled forward Anton Wedin from the Rockford IceHogs in the AHL.
Caggiula suffered his second concussion Nov. 10 against Toronto and has missed all seven games since then. The 25-year-old winger has three goals and four points in 15 games this season in a primarily bottom-six role. He also missed 13 games toward the end of last season with a concussion.
A player placed on LTIR has to miss at least 10 NHL games and 24 days, so the earliest Caggiula could return is Thursday, Dec.
