Coburn (lower body) was designated as week-to-week by coach Jon Cooper, Bryan Burns of the Lightning's official site reports.

EDGE Analysis

Coburn was already placed on injured reserve to free up a roster spot, but the fact that he is considered week-to-week doesn't bode well for a short-term absence. Luke Schenn and Jan Rutta should both see time in the lineup with Coburn on the shelf.
