Doughty (knee) will be activated off injured reserve and play against the Ducks on Tuesday, Zach Dooley of the Kings' official site reports.
Doughty will return to action following a 16-game absence due to his knee problem. Prior to getting hurt, the 31-year-old defenseman racked up one goal and six helpers in four contests. The Ontario native should reclaim his place on the No. 1 power-play unit, as well.
