NOTES: Kings C DeMarcus Cousins (sprained left ankle) and F Rudy Gay (strained left Achilles tendon) did not play against Indiana and, according to coach Michael Malone, might miss at least one more game. "It's honestly too early to tell," Malone said before the game. "I know DeMarcus is dying to play. The good thing is both MRIs didn't reveal anything to us serious. So I'm hoping (they return) in the next day or so, but it could be a couple games. We'll have to re-evaluate it tomorrow with our training staff and see what they're saying." ... Despite his team's injuries, Malone said he still planned to "slowly increase" backup F Carl Landry's playing time as he continues his comeback from a torn left hip flexor muscle. Landry appeared in just his third game this season Friday. "I'm not going to do anything to jeopardize his recovery and all the work he's put in," Malone said. ... Pacers F Paul George appeared in his first game since being voted a starter for the Eastern Conference in the NBA All-Star game and being named in the pool of 28 players for the U.S. men's basketball national team. "Couldn't be more proud," Pacers coach Frank Vogel said. "The kid has worked, he cares. He cares about all the right things. He represents all the right things." ... Pacers F Solomon Hill was inactive for the game.
