In the wake of the Luis Suarez bite incident, former boxing champion Mike Tyson -- who bit Evander Holyfield during a bout in 1997 -- became an involuntary part of the World Cup conversation.

Tyson, of course, was famously upset by Douglas in a championship bout in 1990. At the time, Tyson was the undefeated, undisputed heavyweight champion of the world.
