The return of former WBO heavyweight champion Tommy Morrison has postponed, but not because of his recent blood test. It was reported in The Arizona Republic, that Morrison has  suffered a hand injury that will prevent him from fighting on January 19 in a four-round bout on the undercard of a Showtime televised card from Phoenix, Arizona.

John Montano, head of the Arizona State Boxing Commission, witnessed Morrison take a blood test at a local Phoenix lab, and obtained the official results that showed Morrison testing negative for HIV, the virus that causes AIDS.

Morrison injured his left hand while training on Saturday at Michael Munoz's gym in north Phoenix. A doctor took a look at his hand and would not allow him to fight.

Morrison, 38-years-old, will still work towards obtaining a boxing license in Arizona in order to move forward with his return.

He tested positive for HIV more than a decade ago in Las Vegas, which ended his boxing career. Morrison has maintained for the last few years that he was given a false-positive in Las Vegas. Morrison has tested negative for the virus on 4 occasions since December.
