Warriors swingman Jimmy Butler had an MRI on his sore left knee and did not play against the 76ers on Thursday night. Butler initially took a hard foul in Saturday’s win over the New Orleans Pelicans, but played through the soreness. He started Tuesday’s loss to the Oklahoma City Thunder, but did not return after halftime because of the knee issue. While Kerr and the Warriors don’t seem concerned about the injury, it remains unclear exactly when Butler will return to the floor, given that they have a back-to-back on Saturday and Sunday against the Cleveland Cavaliers and the Chicago Bulls.New York TimesThis article originally appeared on Hoops Hype: Steve Kerr, Warriors not concerned about Jimmy Butler’s injury
