Kevin Durant over the past 10 days has progressed from taking shots from a chair to set shots to firing up jumpers. Though there still is no timetable for his return, Durant will be on the team flight Sunday when the Warriors travel to Oklahoma City. “He’s clearly making progress. It’s great,” coach Steve Kerr said late Saturday afternoon, prior to tipoff against the Milwaukee Bucks. Durant sustained a sprained medial collateral ligament (MCL) and bone bruise to his left knee on Feb. 28 at Washington. He returned to the Bay Area the next day, his leg immobilized in a bulky brace while he moved about on crutches. Scheduled for re-evaluation in about 10 days, Durant is walking comfortably and working up a sweat on the stationary bicycle.
