Tyson used 'fake willie' to fool drug-testers, fought bouts while high on cocaine

Former world heavyweight boxing champion Mike Tyson has made claims in his new book Undisputed Truth that he used a fake willie to fool drug-testers and fought on cocaine.

According to the Mirror, Tyson claims he spent a large chunk of his career addicted to cocaine and marijuana.

He also admits taking drugs before his shock loss to Londoner Danny Williams in Louisville in July 2004 in his memoir published yesterday, the report said.

The New Yorker, who retired in 2005, also admits devising a fake penis, or his 'whizzer' as he called it, to avoid failing drugs tests, the report added.

Tyson says he came up with the idea before his fight against Lou Savarese at Hampden Park in June 2000 and one of his team would bring it to each contest, the report further said.

He admits he had taken 'blow' and 'pot' before the bout and filled his 'whizzer' with someone else's urine to dupe the testers, according to the report.

Tyson, the youngest boxer ever to win the WBC, WBA and IBF heavyweight titles, has retired from boxing and been through years of rehab, the report mentioned.
