Strikeforce and DreamEdit
Overeem finally made his first defense of his heavyweight belt, after three years, against Brett Rogers, winning by dominant technical knockout due to referee stoppage.
He was set to face former UFC heavyweight champion Ricco Rodriguez in Dream but the fight was called off shortly. Overeem was then set to defend his Strikeforce belt against Antonio Silva but that was called off as well. After winning the K1 title in December, Overeem was in talks to face Josh Barnett for the inaugural Dream heavyweight title at the year-end Dynamite show.
Instead, Overeem was set to face fellow Strikeforce veteran and former professional wrestler Bobby Lashley for the vacant title at the event. That fight was called off as well and about a week and a half before the event, Alistair was confirmed to be facing UFC veteran Todd Duffee in a Dream heavyweight interim title fight despite the fact that there had never been an official Dream heavyweight title. Overeem destroyed Duffee in about twenty seconds to earn the belt via knockout.
He next signed to face Fabricio Werdum in the first round of the Strikeforce heavyweight tournament. In May 2011 before the fight with Werdum, rumors floated around about Overeem abandoning the tournament and his title altogether and heading to the UFC. Overeem remained in the tournament and dominated a strangely sedated Werdum, winning via unanimous decision.
With the victory, Overeem advanced in the tournament bracket to face well-rounded Antonio Silva in the semifinal round. Shortly after the bouts were announced for a September event, Overeem dropped out after a dispute between him and Zuffa. He was replaced by Dan Cormier. Overeem's injuries were revealed to be more serious than originally stated, including a broken toe and a broken rib. He was surprisingly cut from the Strikeforce promotion.
Overeem next vacated his Strikeforce title completely and signed with the UFC.
Before the fight, Overeem stated, "This fight isn't going to last two rounds. Mr. Lesnar is the best wrestler in the division, but he has a big weakness: He cannot strike. And unfortunately I am the best striker in the world."
Lesnar responded to Overeem's comments, stating: "He says he is going to knock me out inside two rounds. That's his dream. The reality is if I execute my game plan, Alistair Overeem cannot win this fight."
Overeem stuffed Lesnar's lone desperate takedown, stalking him against the cage and repeatedly landing large knees to the body. Overeem dropped Lesnar two minutes in with a punishing body kick to the liver and pounded him out with punches for the victory; Lesnar talked with obvious respect about Overeem in the post-fight interview before retiring from MMA.
With the stunning victory over Lesnar, Overeem earned a shot at the intimidating UFC heavyweight champion Junior Dos Santos in May 2012. A few months before the fight, Overeem tested positive for steroids from the Lesnar fight and was pulled from the title bout. He was replaced by former UFC heavyweight champion Frank Mir. Overeem was suspended for a full year after the December test.
String of Knockout LossesEdit
After several months of speculation while Overeem was suspended, Alistair was announced midway through November 2012 to be facing fellow Strikeforce veteran Antonio Silva in February 2013. After dominating "Bigfoot" for two rounds, Overeem got overly confident suffering a brutal third round knockout loss to Silva.
After recovering Overeem next signed to fight prospect Travis Browne. After dominating the first round rocking Browne repeatedly with knees to the body in the clinch, Overeem began to tire and his hands dropped and he failed to defend the repeated front kicks of Browne. Browne eventually landed one of the strikes to the chin of Overeem dropping him for a knockout victory near the end of the first round.
Overeem next signed to fight former UFC heavyweight champion Frank Mir. He was quoted as saying "If I lose to Frank Mir I might as well be doing something else." Overeem dominated Mir en route to a unanimous decision.
He was next set to fight Ben Rothwell. Rothwell knocked out Overeem in the very first round. It was Overeem's third knockout loss in four fights.
Overeem wasted little time in signing in September 2014 for possibly his last chance to surge back towards the UFC heavyweight title or indeed even remain on the UFC roster - a December bout against returning veteran Stefan Struve. Overeem knocked out Struve near the end of the first round.
Shortly thereafter Overeem signed to fight veteran Roy Nelson. Overeem dominated Nelson en route to a unanimous decision victory.
Overeem then signed to fight former UFC heavyweight champion Junior Dos Santos. Overeem defeated Dos Santos via a stunning and impressive second round knockout.
Overeem next fought former UFC heavyweight champion and training partner Andrei Arlovski, knocking Arlovski out as well in the second round.
Overeem recived a shot at UFC heavyweight champion Stipe Miocic with the Arlovski win. Miocic unfortunately knocked Overeem out towards the end of an action-packed, back-and-forth first round.
