OMG Pratt had a hernia earlier in the year!
I watched Pratts 2nd round match in full and Keryn Pratt said that she had a hernia in the weeks prior to Fed Cup vs Russia tie. Appraently Nicole was in a special pressurised vest for 23 hours a day, and even played one tournament in it. She needed it so her hernia wouldnt suddenly bulge out LOL.
Thats pretty gutsy from Nicole!
