Athletics' Sean Murphy: Reinjures knee

Murphy reinjured the same knee he had surgery on in May during Tuesday's game for Triple-A Las Vegas, Melissa Lockard of The Athletic reports.

The A's are awaiting further testing before providing a timetable. Murphy was arguably the hottest hitter in the minors, having swatted five home runs in his last four games with eight hits and 13 RBI over that stretch.
