Kaiser was reassigned to AHL Rockford on Thursday, per Charlie Roumeliotis of WGN Radio.
Kaiser has a goal and three points in 35 appearances with the Blackhawks in 2024-25. It's possible Kaiser will be recalled ahead of Friday's tilt, but Chicago still has seven healthy defensemen on its active roster, so it wouldn't be shocking if the 22-year-old blueliner ends up being in the minors for a significant stretch of time.
