Cain had a successful surgery on his injured knee. He wants to be back in the Octogon by March.
"The approximate timetable is that Velasquez will be ready to train again in December, and they are targeting early March for a fight. It is rumored that UFC 184 will be on Feb. 28 at the Staples Center in Los Angeles. With the strong Hispanic population of the Los Angeles market, Velasquez is a natural headliner. He's already fought three times in the market, once at the Staples Center and twice at the Honda Center in Anaheim, including his first title win over Brock Lesnar four years ago. But that date may be pushing it slightly, and it's expected Chris Weidman vs. Vitor Belfort would headline that show. Velasquez against the winner of the Nov. 15 fight between Werdum and Mark Hunt for the interim title could headline in March."
