Steve Kerr missed Saturday's game with what the team described as an "illness," but it appears to be something serious. The Warriors haven't provided specifics of Kerr's condition – reportedly because they don't have any answers yet. According to the San Jose Mercury News, the worst symptoms have left Kerr in excruciating pain and barely able to walk. A spinal fluid leak caused numerous symptoms that included debilitating headaches and nausea, which caused him to miss the first 43 games of the 2015-16 season.
