event and away from it. Forbidden acts frequently include performance-enhancing drug taking (known as "doping"), using equipment that does not conform to the rules or altering the condition of equipment during play, and deliberate harassment or injury to competitors. High-profile examples of alleged doping cheating include Lance Armstrong's use of steroids in professional road cyclingparticularly controversial as it is widely suspected that a high percentage of professional cyclists are using prohibited substancesBen Johnson's disqualification following the 100 metres final at the 1988 Summer Olympics, and admissions of steroid use by former professional baseball players after they have retired, such as José Canseco and Ken Caminiti. A famous sporting scandal involving cheating via harassment and injury occurred in 1994 in figure skating when Tonya Harding's ex-husband, Jeff Gillooly, and her bodyguard Shawn Eckhardt, hired Shane Stant to break Nancy Kerrigan's leg to remove her from the year's competitions and prevent her from competing with Harding. One of the most famous instances of cheating involving a prohibited player action occurred during the 1986 FIFA World Cup quarter-final, when Diego Maradona used his hand to punch the ball into the goal of England goalkeeper Peter Shilton. Using the hand or arm by anyone other than a goalkeeper is illegal according to the rules of association football. Illegally altering the condition of playing equipment is frequently seen in bat sports such as baseball and cricket, which are heavily dependent on equipment condition. For example, in baseball, a pitcher using a doctored baseball, such as a spitball or an emery ball, or a batter using a corked bat are some examples of this. Tennis and golf are also subject to equipment cheating, with players being accused of using rackets of illegal string tension, or golf clubs of illegal weight, size, or make. Equipment cheating can also occur via the use of external aids in situations where equipment is prohibitedsuch as in American football via the use of stickum on the hands of receivers, making the ball easier to catch. An example of this is Hall of Famer Jerry Rice, who admitted to regularly and illegally using "stickum" throughout his career, calling into question the integrity of his receiving records. Athletic cheating is a widespread problem. For example, in professional bodybuilding, cheating is now estimated to be so universal that it is now considered impossible to engage in professional competition without cheating and the use of
