Did a knee injury hold back Cain Velasquez the first time he fought Junior dos Santos? When the two first met up last November, Velasquez reportedly had a badly injured knee. He was knocked out in 64 seconds. This time a (seemingly) healthy Velasquez will get to show if he deserves the heavyweight belt.
Has Chris Leben returned to form, for really real this time? Since Leben was on the original "Ultimate Fighter," he has been a man who wrestled with his demons. Most recently, those demons took the form of a banned pain killer which resulted in a one-year suspension from the UFC. Against Derek Brunson, Leben can show he's again the man who knocked out Wanderlei Silva.
Can Tim Boetsch be the next guy to challenge Anderson Silva? Though his original bout with Chris Weidman was called off because of an injury to Weidman, Boetsch still has another opportunity to show he can beat up opponents. He wants a chance to beat up Silva,* and this bout with Costa Phillippou is an opportunity for Boetsch's fighting to shine.
Or should Alan Belcher be the man to take on Silva? It's been more than three years since Belcher lost a fight. His last four fights have been stoppage wins. An impressive win over Yushin Okami could put him in line to fight for the middleweight belt.*
Is Todd Duffee still the knockout artist who once graced the octagon? Back in 2009, Duffee knocked out Tim Hague in a mere seven seconds. After that, the hype train was running behind him full steam. It was derailed when Mike Russow came back to knock Duffee out in the third round of their bout. Duffee was cut from the UFC, and is getting another shot at the octagon on Saturday. He'll fight Philip De Fries on the Facebook preliminaries, and get a chance to show if he can still knock people out very quickly.
