FanHouse Forrest Griffin

UFC 106 will now be headlined by former light heavyweight champions Tito Ortiz vs. Forrest Griffin at the pay-per-view event on Nov. 21 emanating from the Mandalay Bay Events Center in Las Vegas.

To boost the card due to postponement of Brock Lesnar vs. Shane Carwin until UFC 108 on Jan. 2, Josh Koscheck has been matched with Anthony Johnson in a co-headliner between top welterweights.

Below is the UFC 106 fight card.

In a major blow to the Nov. 21 UFC 106 card in Vegas, the heavyweight championship bout between titleholder Brock Lesnar and challenger Shane Carwin has been scrapped.

Yahoo! Sports is reporting that Lesnar withdrew Monday from the main event due to an illness that has sidelined him from training for over three-and-a-half weeks.

"He said he's never been this sick in his life," UFC president Dana White told Yahoo! Sports. "He said it's been going on for a long time and he just hasn't been able to shake it."

Lyoto Machida is still the light heavyweight champion of the UFC, but not many people agree with the three judges who allowed him to keep his belt after 25 minutes in the Octagon with Shogun Rua on Saturday night.

So does Machida keep his status as the top light heavyweight in MMA in my latest Top 10? He does, but Shogun also moves up in the rankings after a very close fight with the champ. The full rankings are below.

If the Lyoto Machida-Shogun Rua fight at UFC 104 had gone the way everyone expected -- Machida handily defeating Shogun to retain his title -- the UFC would have faced a quandary with its light heavyweight division. Machida would be perceived as so dominant that there wouldn't be any particularly interesting fights for him, and the stacked UFC light heavyweight division might have started to feel a little stale.

That's why Machida's controversial unanimous decision victory on Saturday night was a great thing for the UFC: It sets up a Rua-Machida rematch that will be a bigger fight than the first one, and it buys time for the UFC to re-establish some of its other light heavyweights as contenders to take on the Rua-Machida 2 winner.

It's been a long time since Mauricio "Shogun" Rua has walked into a fight as the underdog, with the odds stacked against him and the fans doubting his ability to win, but that's exactly what he'll face on Oct. 24 when he steps into the octagon at UFC 104 and stares across the cage at unbeaten champion Lyoto Machida.

The last 24 hours have given us some big news on the two biggest MMA cards of the fall: The November 21 UFC 106 got better with Forrest Griffin stepping in for the injured Mark Coleman to face Tito Ortiz, while the November 7 Strikeforce/M-1 Global card got better with Rameau Thierry Sokoudjou facing Gegard Mousasi.

So which card is better: UFC 106: Lesnar vs. Carwin, or Strikeforce and M-1 Global: Fedor vs. Rogers? I asked MMA fans on Twitter to weigh in, and a majority picked UFC. A selection of answers -- plus a bonus question about a fight card that I think might be more fun than either of them -- is below.

Forrest Griffin has stepped into the UFC 106 slot vacated by Mark Coleman due to injury, and will take on the returning Tito Ortiz, according to a report from Yahoo Sports, citing confirmation from UFC President Dana White.

The fight is a rematch of an April 2006 contest, which Ortiz (15-6) won in a tight split-decision.

Coleman was forced to withdraw from the bout just days ago, leaving the UFC scrambling for a replacement. Griffin (16-6), like Ortiz a former light-heavyweight champion, should be considered by most a worthy choice.

Boston Bruins goalie Tim Thomas is such a big MMA fan that he named his dog after Forrest Griffin. (Surprisingly, though, the dog's name is Griffin, not Forrest.) And after to talking to him about his love for all things MMA recently, it's probably safe to assume that few professional athletes enjoy watching the sport more than the veteran netminder.

The winner of the 2009 Vezina Trophy for the NHL's best goaltender discussed how he was drawn to MMA, why he thinks the fighters should get paid more and whether he would ever step into a cage or ring himself. The full interview is below.

Strikeforce heavyweight and international MMA star Fedor Emelianenko is scheduled to fight Brett Rogers on Nov. 7, but during the midst of training, Emelianenko found the time to marry his longtime girlfriend Marina.

The traditional Russian Orthodox wedding took place this weekend in his hometown of Stary Oskol, according to Emelianenko's official Web site.

Forrest Griffin hasn't been heard from much since his UFC 101 loss to Anderson Silva, but that's not to say he hasn't been keeping himself busy. The former UFC light heavyweight champion recently got married, released a new iPhone app and has been working on his second book, not to mention planning his upcoming honeymoon.

FanHouse spoke to Griffin on Thursday about the big changes in his life and when he expects to return to action. The full interview is below.
