Kaiser was sent to AHL Rockford on Friday, per Charlie Roumeliotis of WGN Radio.
The 22-year-old defenseman had been a healthy scratch in the Blackhawks' last three games. Kaiser picked up an assist in his second game of the season but didn't have a point in his past 26 outings. Kaiser will get a chance to play more and regain his confidence offensively with the IceHogs.
