      The 25th seed's fourth round singles match against Italy's Roberta Vinci is also in jeopardy with a decision on whether the tie will go ahead expected late Saturday.
      According to a statement on the U.S. Open website from tournament director, David Brewer, Bouchard's injury will "continued to be assessed by "on-site medical personnel at the U.S. Open."
