Stars goalie Kari Lehtonen, who has missed the last 12 games with a lower body injury, was activated off injured reserve on Wednesday. He will be between the pipes against the Blue Jackets on Thursday. "(Lehtonen) is ready to go. He'll get the start (Thursday) and I think it's the right time to do all this and he's ready," coach Glen Gulutzan said. To make room on the roster, defenseman Stephane Robidas was placed on injured reserve, retroactive to Dec. 19.
