As one of the UFC's most popular fighters and biggest pay-per-view draws, Overeem's comeback will be welcomed with open arms.

Overeem hasn't fought since December 2011 due to a lengthy drug suspension. In his last fight, he just so happened to finish a washed-up Brock Lesnar by kicking his already injured stomach.
UFC 156 will be Overeem's first true test in the deepest heavyweight division in the world as he steps inside the cage opposite Antonio "Big Foot" Silva. Silva is coming off a devastating knockout victory over Travis Browne and could easily prolong success if he's taken lightly.
Here are five keys to victory for "The Demolition Man" as he attempts to re-polish his title-contending image.
