First Title Run Edit
He most recently defeated fellow undefeated prospect Alexander Gustaffson via anaconda choke, handing Gustaffson the first loss of his career.
Fellow debuting undefeated fighter Stanislav Nedkov was injured and had to pull out of his fight with Rodney Wallace. Davis replaced Nedkov to fight Wallace and won via dominant unanimous decision. Davis next faced Tim Boetsch, winning via second-round kimura submission.
He was next set to face veteran Matt Hamill, but the fight was mysteriously called off about two months early. Hamill was switched to face former UFC light-heavyweight champion Quinton Jackson, and Davis remained on the same card as before. Davis was instead set to face the relentless Jason Brilz. Less than a week later, Tito Ortiz pulled out of a bout against Antonio Rogerio Nogueira and Davis stepped in as his replacement. Davis defeated Nogueira via unanimous decision in the biggest win of his career.
Davis next replaced light-heavyweight champion Jon Jones in a bout versus former UFC light-heavyweight champion Rashad Evans. Unfortunately Davis was injured and forced to pull out a few weeks before the bout. Another former champion Tito Ortiz stepped in to replace Davis in a rematch against Evans.
After recovering, Davis next signed to face Rashad Evans again. Evans handed Davis his first loss via a dominant five-round unanimous decision live on the prime-time Fox network. Davis impressed despite losing.
Second Title Run Edit
Davis next faced newcomer and unknown Wagner Prado, who stepped in as a replacement for injured Strikeforce veteran Chad Griggs. Prado suffered an eyepoke early in the fight and it was waved off as a no-contest.
Prado and Davis immediately rematched in Prado's native Brazil, resulting in a second round anaconda choke victory for Davis.
Davis next signed to face former UFC light-heavyweight champion Forrest Griffin at the UFC's New Year's Eve event at the end of 2012. Unfortunately Griffin suffered a bad knee injury early in December 2012.
Davis instead faced bitter rival Vinny Magalhaes defeating Magalhaes via a dominant unanimous decision.
Davis next signed to fight former UFC light-heavyweight champion Lyoto Machida. He defeated Machida via a very controversial unanimous decision in Machida's homeland of Brazil.
Davis was next rumored to fight former Strikeforce light-heavyweight champion Gegard Mousasi.
Instead Davis was on the sidelines for pretty close to a year before signing in February 2014 to fight returning former UFC welterweight and WSOF veteran Anthony Johnson. Johnson dominated Davis en route to a unanimous decision.
Third Title Run Edit
Afterwards Davis signed to fight contender Glover Teixeira. Davis defeated Teixeira via a very convincing and impressive but not exactly entertaining unanimous decision.
He then fought fellow contender Ryan Bader in another unentertaining bout that resulted in a grueling split decision loss for Davis.
As a free agent after the Bader loss Davis then signed with Bellator. In his Bellator debut, in a one-night light-heavyweight tournament, Davis defeated former champ Emanuel Newton via a first round kimura submission before then knocking out Francis Carmont in the first round.
Davis dominated McGeary completely en route to a unanimous decision victory to become the fifth Bellator light-heavyweight champion.
Several months of inactivity later Davis was called out by newly signed UFC rival Ryan Bader for a title rematch at the biggest event to date in Bellator history, a June pay-per-view event in Madison Square Garden. Davis eagerly accepted. Bader defeated Davis via a tepid split decision victory.
