UFC 155: Dos Santos vs. Velasquez 2

Background

This will be UFC's last event of the year. In the main event the champion Junior Dos Santos fought Cain Velasquez for the heavyweight championship. The first time that they met each other inside the octagon Dos Santos was able to KO Velasquez and become the UFC champion. After losing to Dos Santos, Velasquez had a great performance against Antonio Silva that earned him a title shot.  Dos Santos did a good job stuffing Velasquez's takedowns throughout the fight, but took a hard punch in the first round that he never seemed to fully recover from.  Velasquez kept pressure on dos Santos for all 5 rounds but was unable to finish him.  Velasquez won a unanimous decision and the UFC heavyweight title.

Chael Sonnen was supposed to face Forrest Griffin but he got an offer to participate on the next American TUF against Jones. Then Griffin was set to fight Phil Davis who was coming off a win over Wagner Prado at UFC 153.  Griffin was injured before the fight, and the bout was scrapped.  Added in its place was the Melvin Guillard vs Jamie Varner, rescheduled from the TUF 16 Finale after Varner pulled out the day of the event due to illness.  Varner defeated Guillard by split decision.

Chris Weidman vs Tim Boetsch was booked for this card, but Weidman had to pull out with an injury and was replaced by Costa Philippou.  Philippou upset Boetsch by 3rd round TKO.

After canceling a title fight twice against Jose Aldo, Erik Koch was scheduled to face Ricardo Lamas at UFC 155, but the bout was rescheduled for UFC on FOX 6. 

This card also featured a lightweight clash between top contenders Joe Lauzon and Jim Miller.  Miller dominated early, bloodying Lauzon in the first round, but Lauzon battled back and kept it an exciting fight.  Miller won by unanimous decision. 

In a rematch 6 years in the making, Alan 'The Talent' Belcher looked to avenge his 2006 loss to Yushin 'Thunder' Okami, but fell short, losing a unanimous decision. 

UFC 155 also marked the much anticipated return of Chris 'The Crippler' Leben as he took on Derek Brunson, but Brunson was able to win a decision over the veteran, despite making his UFC debut on short notice.

Also returning after his surprise release from the UFC in 2010 was Todd Duffee. He went 1-1 since his release with a KO loss to Alistair Overeem at K-1 Dynamite!! 2010 followed by a KO win of his own over Neil Grove at SFL 2 in April 2012. He faced off against Philip De Fries at UFC 155, and won by first round TKO.

The "of the night" bonuses were not difficult to determine since there were only two knockouts and one submission. The knockout award went to Todd Duffee while John Moraga snatched the submission award. Jim Miller and Joe Lauzon earned the fight of the night with their incredible performance.
