The ball is still in Kawhi Leonard’s court when it comes to a return. Spurs coach Gregg Popovich said before Wednesday’s game against New Orleans that the All-Star forward is back in San Antonio and “working hard” at a comeback. “He’s doing what he’s supposed to do,” Popovich said. “He’s working hard at it. He wants to get back, and when and if he feels like he’s ready to go, he will be there.” Leonard has missed 53 of the Spurs’ 62 games, including Wednesday against the Pelicans, while battling the effects of right quadriceps tendinopathy. He has not played since a Jan. 13 victory over Denver. Last week, Popovich said he would be “surprised” if Leonard played again this season. At the time, Leonard was in New York, rehabbing his quadriceps and seeking additional consultation with doctors. With Leonard having resumed his workouts in San Antonio, there is hope for a mid-March return. New Orleans coach Alvin Gentry laughed at the suggestion that the Spurs — 36-25 entering Wednesday — were struggling without their star player. “When you’re third in the West and survive without arguably one of the top-five players in the league — and no argument on him being the best two-way player in the league — you’re still OK,” Gentry said.
