Very few boxers retire on their own. They are normally beaten into retirement and even then if they can find a fight, they will keep fighting.
9 times out of 10 it is because they need the money and Antonio Tarver is no exception. He was released from jail on March 5th for not paying a $200k Gambling Debt. He still owes the debt, so he will be fighting on September 19th in San Antonio against Johnthan Banks. Banks is no bum, so I give Tarver credit for fighting someone with a pulse.
In an interesting twist, Tarver’s son will be on the undercard.
