The Columbus Blue Jackets will be without Lukas Sedlak for approximately six weeks after the forward suffered an ankle injury in today’s practice. Sedlak has been placed on injured reserve, while Columbus has recalled Markus Hannikainen to replace him on the roster.

While Sedlak isn’t an integral part of the Columbus offense—he’s played an average of just 9:58 through the first eight games—losing him for six weeks will continue to test their depth.
