Christiansen was returned to AHL Cleveland on Friday, according to Aaron Portzline of The Athletic.
Christiansen played three games with the Blue Jackets during his recent call-up, picking up one assist. He has five goals and 22 points in 28 AHL contests this season. The move opens up a roster spot allowing the Blue Jackets to activate Adam Boqvist from injured reserve in time for Saturday's game versus Minnesota.
