Tyson will return to the ring on 2 October in Las Vegas for his first fight since stopping Francois Botha in the fifth round in January. If all goes well Tyson will fight again on 11 December on a pay-per-view card. Both fights are to be held at the MGM Grand hotel-casino in Las Vegas.
No opponents have been selected for either fight, but Tyson's first contest could be against the Croat Zeljko Mavrovic or Axel Schulz of Germany. The fight would be televised on the Showtime cable network, making it Tyson's first non pay-per-view bout since he stopped Buster Mathis in December 1995.
Should Tyson win, his second outing is expected to be against an upgraded opponent along the lines of Andrew Golota or Shannon Briggs.
The 33-year-old former heavyweight champion has fought only once - against Botha - since his infamous biting of Evander Holyfield's ears in June 1997.
The most feared heavyweight of his time in the late 1980s, Tyson has fought only 12 times in the last decade, winning nine and losing three.
Tyson, who split with promoter Don King after accusing him of taking more than $100m in his earnings, has been in Phoenix for the past month, shedding weight to get ready for the sparring portion of his training regime that will begin sometime in the next two weeks.
Tyson weighed the heaviest of his career when he fought Botha 15st 13lb (223lb) and reportedly weighed 19st 9lb (275) when he was released from a Maryland prison in May after his latest jailing for attacking two men following a road traffic dispute.
