Wanderlei Silva's Crusade Against Retirement On The Round-Up

MMA Nation Round-Up provides you with daily coverage of the latest in news, multimedia, and analysis throughout the world of combat sports. This morning we look back at the UFC on Fox ratings before turning our gaze to the UFC 139 promotional push. Plus Shane Carwin's back surgery and Anderson Silva's stewing beef with Ed Soares.

- Wednesday's UFC 139 media conference call was jam-packed with tidbits from headliners Dan Henderson, Wanderlei Silva, Mauricio "Shogun" Rua, and Cung Le. MMA Nation has complete coverage of the call, including audio.

- The UFC on Fox peak ratings were unveiled on Wednesday, and they surpassed even the most generous of predictions. Afterward, many within the community took to Twitter to express their pleasure.

- Alistair Overeem isn't the only one unhappy with his management. UFC middleweight champ Anderson Silva spoke to MMA Nation and dropped this doozy: "It's a problem. It's a big problem. I don't like the picture, I don't like the position my manager (was in). Big problem. I don't like it." 

- After all the history between Michael Bisping and Dan Henderson, you'd think the affable Brit would hold a grudge. Not so, apparently, as Bisping hopes Henderson wins his fight against Shogun Rua at UFC 139 for one reason: "because it makes me look better."

- New York's ongoing crusade against mixed martial arts hit another convoluted snag this week, as Zuffa filed suit against the state for "blatant violation of the First Amendment of the Constitution." MMA Nation's Jonathan Snowden spoke to UFC attorney and New York University Law Professor Barry Friedman to uncover the details of the case.

- UFC heavyweight contender underwent major back surgery this week after sitting on the shelf since June. He released this photo via Twitter following the successful procedure. 

- Money burning a hole in your pocket? Check out the UFC 139 betting lines. Henderson at +110 looks mighty interesting.

- Rafael dos Anjos isn't ready to rest on his laurels. Fresh off a stunning knockout of George Sotiropoulos, the Brazilian traveled to the United States to train wrestling in preparation for his UFC 139 tilt with Gleison Tibau.

- While the legend of Wanderlei Silva will never die, his current iteration leaves something to be desired. Leland Rolling explains: "The reality of Silva's career at this juncture is quite clear. It really isn't about winning per se."

- Despite the criticism, Silva isn't ready to retire just yet. Watch as he trains with Mark Munoz, Brendan Schaub, Krzysztof Soszynski, and Jake Ellenberger in preparation for his co-headlining bout at UFC 139.
