The Dallas Stars will have to shuffle their lineup after Jason Spezza sustained an upper-body injury in a 4-3 loss to the Winnipeg Jets. He will miss a week or two, possibly longer, coach Lindy Ruff said Friday. Forward Curtis McKenzie will dress after being scratched the past two games. The Stars are 0-2-1 against the Blackhawks this season. "We've had some missed opportunities against this team," Ruff said. "We had a chance in overtime in their building and didn't put it away. So there's been opportunities and we just quite haven't got it done." Dallas is 8-10-4 against the Central Division and enters Saturday four points out of the second wild card into the Stanley Cup Playoffs from the Western Conference. Forward Jamie Benn has seven points (four goals, three assists) during a season-high five-game point streak. Benn had a goal and two assists against Winnipeg. "Puck was on his stick, it was probably his best night with his own puck possession creating his own opportunities," Ruff said. Goalie Kari Lehtonen will make his third straight start and 10th straight appearance after allowing four goals on 29 shots against Winnipeg.
