Fabbro (upper body) is expected to miss at least a month, Aaron Portzline of The Athletic reports Sunday.
Fabbro was placed on injured reserve Friday due to an upper-body injury he sustained during Monday's preseason game against the Red Wings. It's not yet clear whether Damon Severson (shoulder) will be ready for Opening Night, but the Blue Jackets are in the process of trying to sign Carson Soucy after he spent camp with the team on a professional tryout agreement.
