Arnett might have torn ACL

MLB.com reports Brewers prospect Eric Arnett will be evaluated Wednesday for a potential torn ACL in his right knee. If surgery is required, then it will be on Thursday. "He was much better. There was some optimism there," assistant GM Gord Ash said. "In short spurts, he appeared to be more comfortable, so this is definitely a setback. But [assuming he needs surgery], he will just have to get geared up for instructional league and make up for lost time."
