Doughty appeared to hurt his left shoulder while delivering a check to Sharks forward Tyler Kennedy. He played 5:21 in five shifts but did not see the ice after 8:42 of the period. The Kings announced midway through the second period that Doughty would not return.
"He didn't feel good enough to come back," Kings coach Darryl Sutter said after the 2-1 loss.
Sutter had no update on Doughty's condition after the game, but the Kings said the defenseman will travel with the club for its game against the Vancouver Canucks on Saturday night.
If you want to prove people wrong, you've just got to go out and do it. Yeah, we blew 3-2 series leads the last two years, but no one is going remember that if we go out there on Saturday night and beat these guys and go play in the Stanley Cup Final. We need to get back to work and we'll start to do that tomorrow.
