Olympic swimming gold medalist Missy Franklin could miss the Pan Pacific Championships in Australia after experiencing back spasms during a practice Tuesday.
USA Swimming announced in a press release that her status will be determined "prior to preliminary heats on Thursday morning."
Franklin tweeted after the practice that she was "already feeling better," then said Wednesday that she is "feeling drastically better every hour that goes by and hoping and praying that I will be ready to race tomorrow."

USA Swimming reports that Franklin swam in a local pool Wednesday to test her back and felt "minimal discomfort."
The 19-year-old is scheduled to participate in the 200-meter freestyle and 100-meter backstroke.
Franklin won four gold medals as a 17-year-old at the 2012 Olympics in London. Last year, Franklin became the first woman to win six gold medals at a single World Championships.
