Mitchell Robinson, a five-star freshman enrolled at Western Kentucky, has unexpectedly left the school's campus in Bowling Green and created an uncertain future with the Hilltoppers, a source told CBS Sports on Friday. The source said Robinson had been attending classes and working out for the past two weeks but then didn't show up for a scheduled workout Thursday, at which point the WKU staff went to check on him. His room was empty, according to the source. "It had been cleaned out," the source said. According to the source, nobody at Western Kentucky has spoken with Robinson or his mother since Robinson left campus.
