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.
We never really stopped believing in ourselves. We were hearing a lot of things about our team in the regular season. Seems like we put things back together at the right time and we're back in the finals with this group. We know what we have in this room, we believe in each other, we believe in the organization and it really matter what other people say.
