Koscheck, Johnson agree to replace Lesnar/Carwin at 106

Just days removed from his thoroughly dominating performance over Yoshiyuki Yoshida at UFC 104, Anthony Johnson has agreed to fight another Yoshida victor in Josh Koscheck as a fill in for the Lesnar/Carwin main event at UFC 106.

The news comes according to Sherdog.com which has a source close to Koscheck's camp. Koscheck even twittered that he would be fighting in the 106 main event.

"I got some big fight news for me," Koscheck wrote. "I am fighting Nov. 21 in Vegas. Co main event!! Haha it's on baby!!!"

On Monday, Lesnar officially announced that he had to pull out of the November 21st match-up due to being unable to overcome an illness that has drastically affected his training. The announcement left the UFC with a Texas-sized hole in its pay-per-view event so it rushed to fill that void. Johnson and Koscheck answered the call.

It will be a critical fight for both welterweights as they look to improve their standing in the division. Both fighters are right on the edge of the top five in the division, needing perhaps two more top five wins to earn a shot at champion Georges St.-Pierre.

While Johnson is coming off the big win over Yoshida, Koscheck is coming off a likewise impressive performance from his fight with Frank Trigg at UFC 103. Koscheck is a veteran All-American collegiate wrestler who has faced all the top guys in the division while Johnson is the up-and-coming prospect with impressive wrestling credentials as well. Should be a great test for both fighters.

UFC 104 -- Post event analysis

With UFC 104: Machida vs. Shogun now in the rearview, it's time to look at how the event helped or hurt each of the top fighters involved.

Anthony "Rumble" Johnson: It took him barely 50 seconds to overwhelm Yoshida but then again let's hope he's able to beat someone he was probably 30 lbs heavier by the time the fight started. Plain and simple Johnson is a beast at welterweight. For him to cut down to 170 from weighing about 215 every day is huge for that weight class. There aren't going to be a lot of guys that can deal with what he can bring to the table. His next fight should be a big step up in competition, perhaps somebody like Josh Koscheck.

Joe "Daddy" Stevenson: Listening to him in the post fight press conference was like watching a kid at an amusement park. He was just so excited about his new found game, it was really interesting to hear him speak about being re-energized and excited to put his repertoire into action. Stevenson remains one of the top lightweight fighters in the UFC, perhaps a fight with Gray Maynard or Frank Edgar.

Cain Velasquez: Absolutely dominated Ben Rothwell as I thought he would. Rothwell is an overrated fighter, after all he was fighting in the IFL for a reason. Velasquez on the other hand is a very talented prospect and that is why the UFC picked hip up at the starting point of his career. At 7-0 and with some top wins in his last two fights, Velasquez is really positioning himself for a run at a title fight. I think he needs one more top win before getting that shot and I think he should have to fight Frank Mir provided Mir beats Kongo at 107.

Shogun: Looked like the Rua we've all been waiting to see in beating up Machida. "The Dragon" was thoroughly confused in how to deal with Rua's Muay-Thai. Shogun won that fight but was handed probably the worst decision in MMA history when he was robbed of the title. Now he's left having to repeat what he just did a few months down the line after Machida has had a chance to recover and work a new gameplan to try to compensate for what Shogun wants to do.
