Fabbro sustained an upper-body injury during Monday's preseason game against the Red Wings and will not return.
Fabbro didn't play in the second period after logging one block and one hit in 6:58 of ice time in the first. The Blue Jackets will continue their preseason schedule in the second half of a back-to-back Tuesday in Buffalo -- an update on the right-shot blueliner's status might be available before puck drop, though that's not a guarantee.
