Lindgren (upper body) is expected to be sidelined for 2-3 weeks, Vince Z. Mercogliano of USA Today reports Wednesday.
Lindgren was injured following a fight with Scott Mayfield on Tuesday and now seems set for a stint on the sidelines. If he is back on the short end of that 2-3 week timeframe, the blueliner could still return to action to face the Penguins on Oct. 9. Connor Mackey could see an uptick in ice time during Lindgren's potential absence.
