A source close to the situation spoke to MMANews.com’s Michael Moody on a condition of anonymity and explained that the blood tests came back right before Aleks and Buentello were scheduled to weigh in and that is why there was so much confusion around the stage and why the fighters did not weigh in. Gary Goodridge ended up stepping up on extremely short notice and filling in for the Russian heavyweight.
The tests were positive for Hepatitis B which resulted in the CSAC cancelling the fight. Hep B is the result of transmission from exposure to infectious blood or body fluids containing blood.
Hepatitis B:
Hepatitis B virus infects the liver of hominoidae, including humans, and causes an inflammation called hepatitis. It is a DNA virus and one of many unrelated viruses that cause viral hepatitis. The disease was originally known as "serum hepatitis" and has caused epidemics in parts of Asia and Africa. Hepatitis B is endemic in China and various other parts of Asia.The proportion of the world's population currently infected with the virus is estimated at 3 to 6%, but up to a third have been exposed. Symptoms of the acute illness caused by the virus include liver inflammation, vomiting, jaundice, and rarely, death. Chronic hepatitis B may eventually cause liver cirrhosis and liver cancer, a fatal disease with very poor response to current chemotherapy. The infection is preventable by vaccination.
This would be horrible news for his career!
