Goaltender Kari Lehtonen is expected to start for the Dallas Stars, who are 0-2-1 after three games of a four-game road trip. He's lost three consecutive games since Nov. 17 when he made 34 saves in a 3-2 win against the Colorado Avalanche. The Stars placed forward Patrick Sharp on injured reserve Saturday, retroactive to Dec. 1. Sharp played in the past seven games after missing 14 when he was injured Oct. 20 against the Los Angeles Kings. "He has concussion symptoms," coach Lindy Ruff said. "We don't know if it's related to the previous one, but he's going to be evaluated. It's something he missed a long time with, something we want to be real careful with." The Stars had 35 shots on goal in each of their past two games, a 3-1 loss to the Detroit Red Wings on Tuesday and a 6-2 loss to the Pittsburgh Penguins on Thursday. "We've done a lot of good things the last two games," Ruff said. "The score looked ugly in the last game, but it was really a 3-2 game. We took some chances in the end and missed way too many opportunities. I've liked probably five of our last six periods and we've got nothing for it. We've got to change that."
