Gudbranson (upper body) was placed on injured reserve Thursday.
Gudbranson suffered an upper-body injury during Tuesday's game against the Panthers, and head coach Dean Evason said after the game that the injury was "not looking good." As a result, it's not very surprising to see Gudbranson land on IR, but it's not yet clear when he'll be in the mix to return. David Jiricek could take on a third-pairing role for the Blue Jackets in Gudbranson's absence.
