Lamar Odom hurt his left shoulder when he fell to the court after making a driving layup in the fourth quarter of the Lakers’ victory Wednesday over the Phoenix Suns. He vowed to play in Friday’s game against the New Orleans Hornets at Staples Center. Officially, Odom is said to have a sore left shoulder. “I’m going to have to play right-handed,” he said when reporters quizzed him about his injury after Thursday’s practice in El Segundo. “It’s going to be kind of crazy. I don’t know how I will pull that one off, but I’ll have to try.”
