Despite a left ankle injury that forced him to sit out a portion of the fourth quarter and all of overtime in the Spurs’ 110-107 win Tuesday night, forward Kawhi Leonard vowed to play in Game 6 at Houston on Thursday. “Yeah, I'm going to be able to play,” Leonard said. “It was frustrating because I wanted to play. But I was happy seeing my teammates out there putting in a good effort and getting the win.” Leonard was hurt when he landed on the foot of Houston guard James Harden with 5:37 left in the third quarter. He went to the bench briefly during a timeout, re-tied his shoe and returned to the game.
