Those were a costly few seconds in Philadelphia. Flyers rookie forward Zac Rinaldo managed to take out Drew Doughty, the Kings' top defenseman, and Dustin Penner, one of their top six forwards, in one first-period flurry. Rinaldo could have probably glared at someone and caused another injury the way things were going. Doughty will sit out the Kings' Staples Center opener Tuesday night against the St. Louis Blues. He has an injured right shoulder, and the severity of the injury has not been fully disclosed. The Kings are saying he could be out at least seven to 10 days.
