Lehtonen was injured in a 4-3 win over Minnesota on March 8 when Erik Haula ran him over and knocked off his helmet. He went through his first full practice Friday.
Tim Thomas made four starts in Lehtonen's place, including a game against Columbus that was postponed when Stars forward Rich Peverley collapsed on the bench in the first period. Thomas was acquired from Florida a day before the trading deadline.
Thomas was pulled from Sunday's 7-2 loss at Winnipeg after allowing his fourth goal on 17 shots just 29 seconds into the second period. Nilstorp finished the game.
You get the right the whistles at the right times, you can leave him out there. He's a beast when it comes to being on the ice. I thought [Saturday] he was a big man. That first period, he did that lateral cut and it was like three bowling pins bounced off him. There's not too many guys that can do that.
