Though Comcast and Fox's networks did reach a deal to bring Fuel to its subscribers, the channel won't yet be available for this weekend's bouts and the interesting card in England. No matter who tunes in, here are the intriguing questions around this weekend's bouts.

Is welterweight a better UFC fit for Jorge Santiago? Despite a long and successful career in Sengoku and Strikeforce, his last stint with the UFC didn't go so well. Santiago lost to Demian Maia and Brian Stann. After a first-round knockout in the Titan Fighting Championships, Santiago is back as a welterweight. He'll take on undefeated phenom Gunnar Nelson.

(Getty)Happy Valentine's Day, Cagereaders! In honor of the day, let's take a look at some reasons to love mixed martial arts.

Heavyweight division to love. Remember when the UFC heavyweight division was a joke? No longer. UFC 160 will feature a title bout between Cain Velasquez and Antonio Silva, and Junior dos Santos will fight Alistair Overeem.

So much MMA on television. MMA was once the province of pay-per-view and occasional specials on network and cable television. Now, with Bellator on Spike, the UFC on Fox's networks, and the World Series of Fighting on NBC Sports Network, a fight fan doesn't have to drop $55 a month to see any fighting at all.

(Getty)If like me, you get your cable via Comcast, the UFC's deal with Fox has been a big bag of frustration. Fuel, the channel that carries UFC fights events, preliminary bouts, isn't carried by Comcast. I live in a high rise apartment building with no choice of cable providers, so I was stuck. I heard from many Cagereaders that I wasn't alone in this predicament.

Good news -- Comcast and Fox have finally reached a deal. Comcast's Xfinity subscribers will have access to Fuel and all of its UFC-centric programming.

Now, we don't yet have the details on when Fuel will be available. It is not expected to be in place in time for this weekend's fights on Fuel. But a quick check of On Demand showed that it's already chock full of free Fuel content so Comcasters can watch some Fuel programming now.

Last week's "The Ultimate Fighter" knockout was memorable, so how do you try to top that? A rap battle, some blood and a hospital gown.

Adam Cella still in his hospital gown. Fresh off last week's stunning knockout by Uriah Hall, Cella returned to the TUF house still wearing his hospital gown. He was not seriously injured, but did have to go over the details of the fight with teammates to know exactly what happened. He also nearly joined Hall in the shower to congratulate him.

Rap battle? Rap battle. Gilbert Smith made fun of Kevin Casey for his rapping, specifically this video.

This turned into a rap battle with several fighters participating, and Casey emerging as the clear winner.

Don't mess with people's sleep. When power went out at the TUF house, Team Sonnen thought it would be a good idea to run into Collin Hart's room and throw toilet paper at him as he slept. No, I don't get it, either. But with Hart preparing to meet Casey, he did not want his sleep messed with. Hart was so heated about it that he put up his middle finger during the post-weigh in staredown.

Hart breaks Casey. In a bloody battle, Hart starts with a jumping kick and follows it with a takedown. From there, Hart controls the entire fight. UFC president Dana White is impressed, saying, "It's almost like he broke him." Hart takes the fight 20-18 on every card.

With Hart's win, Team Jones wrested away control from Team Sonnen. The next bout is Bubba McDaniels and Kelvin Gastelum. What did you think of this week's episode? Speak up in the comments, on Facebook or on Twitter.

(Updated with quotes from Reuter via telephone at 6:38 p.m. ET on Feb. 8, 2013)

Collin Reuter's knockout of Gerald Fike on Feb. 1 in Fairbanks, Alaska, wasn't nearly as violent as the one Uriah Hall scored on Adam Cella on Episode 3 of "The Ultimate Fighter." The Hall knockout was promoted heavily for more than a week by the UFC and FX and was definitely worth the hype.

Reuter's knockout was pretty run of the mill, particularly compared to Hall's. But Fike's fall, in which he lands on his head, may go down as the most unique fall ever after a KO.

Early in the first round, Reuter caught Fike on the head with a right hand during a bout on the Solid As A Rock Fighting Championship card. That was enough to end the bout at just 26 seconds nd get the crowd into it.

It wasn't the punch, though, that was so memorable. Instead, it was Fike's reaction. He fell backward after taking the shot. As he did, he arched his back. He thus hit the canvas first with his head. His feet were firmly on the

The first women's fight in UFC history is a little more than two weeks away, and the UFC has created a compelling preview show to chronicle bantamweight champion Ronda Rousey and challenger Liz Carmouche as they prepare for their Feb. 23 match at UFC 157 in Anaheim, Calif.

Liz Carmouche (Getty Images)The show, "UFC Primetime: Rousey vs. Carmouche" is extraordinarily touching. Rousey discusses her relationship with her late father and the regimen she goes through to prepare for a bout.

It documents her personal struggles after winning a bronze medal in judo at the 2008 Olympics and how she found her way into MMA. The segment in which Rousey recalls her father, his illness and eventual death is very powerful.

A former Marine who served three tours in Iraq, Carmouche discusses her homosexuality and the work ethic that has helped her become the No. 1 bantamweight challenger.

The show debuts tonight at midnight ET/9 p.m. PT. The UFC has full listings for the show on its site.

(USA Today Sports Images)Before we start a long and fun stretch of MMA, Cagewriter will be off from now through Tuesday. I'll return on Wednesday, Feb. 12 to talk about the latest episode of "The Ultimate Fighter," the upcoming Bellator and UFC fights, and whatever other craziness may come up in MMA. In the meantime, follow Yahoo! Sports MMA and enjoy one of the few slow times that happen in MMA.

(Getty)UFC on FX 7 happened weeks ago, but drug testing results just became public today. One fighter tested positive for a banned substance, while another was given a testosterone therapeutic use exemption.

-- Thiago Tavares, who lost to Khabib Nurmagomedov, tested positive for drostanalone. He is suspended for nine months, and will have to submit a clean drug test before he fights again. Taking a long break from fighting could hurt Tavares financially, because he only fought once in 2012.

-- Vitor Belfort received a therapeutic use exemption for the use of testosterone. The UFC said he was diagnosed with hypergonadism. Belfort tested positive for an anabolic steroid in 2006, and rumors swirled that he was the fighter who tested positive. UFC president Dana White said after Saturday's fights that it was not Belfort.

These fights were the first ones governed by Brazil's sports commission, and the testing was done by an independent lab.
