Mike Tyson is looking outside boxing to pay some of his debts.
The former heavyweight champion has signed a deal with a martial arts promoter in an effort to diversify his income. The agreement, according to Japan's K-1 organization, gives it certain management rights and rights of refusal for Tyson's activities in Japan.
It apparently, however, doesn't call for Tyson to engage in a martial arts contest with K-1 star Bob Sapp, who Tyson challenged after viewing one of his matches in Las Vegas earlier this month.
Tyson, who hasn't fought since stopping Clifford Etienne in February, recently filed for bankruptcy protection in New York. Recent filings indicate Tyson owes $17 million in back taxes and another $10 million in other debts.
