Corey Crawford, who has been out since the middle of December after suffering his second concussion in two years, was activated by the Chicago Blackhawks on Monday.
The team sent goalie Collin Delia to Rockford of the AHL in a corresponding move.
In a Dec. 16 game against the Sharks, Hawks forward Dylan Strome was pushed into Crawford who went backward and hit his head on the post.
The 33-year-old Crawford, who has won two Stanley Cups with the Blackhawks, missed the final 47 games last season while dealing with lingering concussion symptoms.
