Nick Diaz Hospitalized after EXC
Nick Diaz has been hospitalized with a severe staph infection that he contacted a few days prior to his EliteXC fight. He was admitted to the hospital when he arrived in Las Vegas to watch his brother's fight. He has been on an antibiotic IV since Tuesday and will probably remain so through the weekend.
“I felt pretty crappy in my match in Hawaii but I figured it was jet lag or maybe something I had eaten the night before. When I left Hawaii the next day I was getting chills and had to be covered with several blankets on the plane but I just kept having cold sweats. By the time I got to Vegas the infection had ballooned up and so I went to the hospital to have it checked out. They admitted me and I've been here ever since”.
