Dallas goaltender Kari Lehtonen left Friday night's game against the Winnipeg Jets early in the second period, stopping all 21 shots he faced to that point. Stars coach Lindy Ruff said the injury is day-to-day.
"Encouraging that [Lehtonen] could be back at practice [Sunday]," Ruff said.
Ellis made his first appearance of the season Friday against the Jets and allowed one goal on 23 shots.
Minnesota will go with its own backup goaltender for the second straight game in Josh Harding. Niklas Backstrom, injured Tuesday night against the Nashville Predators, practiced Friday and took part in the morning skate Saturday, but is still unavailable. He is expected to join the Wild on a seven-day, four-game Eastern Conference road trip starting Monday at the Buffalo Sabres.
Darcy Kuemper, called up from the AHL's Iowa Wild on Thursday, will back up Harding, who started and won 2-1 Thursday against the Jets. He has made two appearances this season, stopping 33 of 35 shots overall.
Here are the projected lineups for Saturday's contest between the Stars and Wild:
Brendan Dillon - Stephane Robidas
Matt Dumba - Clayton Stoner
