Apparently Irina is still on medication, and is on a very reduced practice schedule. There are less than 10 weeks to Worlds. If she really wants to be competitive, she would have to increase her practices drastically, and that can't possibly be good for her health.
I hope she takes the time to heal completely before jumping back into a competition such as Worlds were there are three segments to be skated.
The information from this article came from Irina's PR person. The thought has crossed my mind that it isn't really Worlds Irina is aiming for, but the COI tour. I am sure she needs the money now, what with her mother's and her own illness, and having lost income from the two cheesefests and the Grand Prix.
