NOTES: Sacramento F Omri Casspi started in place of Rudy Gay, who sustained a corneal abrasion of his left eye in Monday night's 129-128 double-overtime loss to Charlotte. Gay is listed day-to-day. "I'm hoping we'll get him back on the road trip," said coach George Karl, whose Kings visit New Orleans on Thursday and Memphis on Saturday. ... Sacramento C DeMarcus Cousins entered the game averaging 52 points in his previous two games. "These were special games -- games we'll remember for a long time," Karl said. "We ran into two teams that didn't have a lot of size, and we got the ball to him in a very efficient way, but he was also a very efficient player at a high level. It was fun to watch." Portland coach Terry Stotts, asked how he would describe Cousins' recent play: "I don't know what the word would be. He is doing some things that haven't been done in a long time. It's admirable to watch and a challenge to prepare for."
