Morton left Saturday's start at Milwaukee due to a left knee injury, Jim Salisbury of CSN Philadelphia reports.
Morton took a tumble while attempting to run out a bunt in the top of the second inning. On replays, he appeared to hyperextend his knee, but the Phillies will surely provide a more apt diagnosis in the near future. While Brett Oberholtzer took over for the Phillies on the mound, Morton's next scheduled start, Friday against the Indians, is in question.
