San Antonio Spurs forward Kawhi Leonard expects to play in Game 6 against the Houston Rockets on Thursday night despite a left ankle injury.Leonard rolled his ankle with 5:37 left in the third quarter on Tuesday night and played half of the fourth period but did not take the court for overtime of the Spurs' 110-107 home win to take a 3-2 lead in the best-of-seven Western Conference semifinal series."Yeah, I'm going to be able to play," Leonard said after the game. "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 suffered the injury when he came down on the foot of Houston's James Harden while turning to run up the court. Leonard limped back to the bench during the next stoppage in play and re-entered the game but did not score after a layup with 1:59 to play in the third quarter.The 25-year-old Leonard still led the Spurs with 22 points and 15 rebounds. He is averaging 27.8 points, 7.7 rebounds and 4.7 assists during the postseason.Spurs coach Gregg Popovich said Leonard asked to stay in the game but the staff made the decision to pull him."He's had issues, and you could tell just before he took a couple of shots he jumped off one foot," Popovich said Tuesday night. "He didn't want to come out, obviously. We let him play a little while just to see what he was going to be like, but it was obvious that he couldn't go. So I think everybody else picked it up very well."Game 6 is Thursday in Houston and the winner of the series will take on the Golden State Warriors in the West finals."It's going to be tough. They're a great offensive team," Leonard said of Game 6. "They're a bunch of competitive guys. They play great at home. It's going to be tough. It's going to be about taking care of the ball, playing confident and trying to minimize our mistakes."
