When Georges St-Pierre starts rolling, there is no stopping him.

The UFC welterweight champion has been out for 18 months and he insists that Carlos Condit, the man who won the interim belt in his absence, is the division's "real" champion.

"Look at the guy, what he's done," St-Pierre said. "He's been fighting and winning against all the great fighters. That's what the champion does."

Condit, though, who fights St-Pierre in the main event of UFC 154 at the Bell Centre in Montreal, doesn't feel much like a champion. The UFC pitted Condit against Nick Diaz for the interim title at UFC 143 back in February, when it was clear St-Pierre's injured knee wouldn’t be ready. Condit executed a perfect gameplan in the fight, dissecting Diaz for a unanimous decision win to earn the interim belt.

So, in a way, Saturday's bout will be a unification bout, though the interim title will disappear regardless of who wins.

Condit, though, pleads with almost as much urgency as St-Pierre

Give this to Adrien Broner: The man doesn't think small.

The unbeaten former super featherweight champion doesn't want to simply become known as the greatest fighter ever from Cincinnati, where he was born and raised, and still lives.

He's got much loftier goals than that.

"Adrien Broner not only wants to be the best from Cincinnati, but the best boxer ever to lace up a pair of boxing gloves," Broner said. "That's the conversation I want my name in."

Just becoming the greatest from Cincinnati is going to be a massive accomplishment for the brash 23-year-old, who meets Antonio DeMarco on Saturday in Atlantic City, N.J., for the WBC lightweight belt in a bout televised nationally by HBO.

The finest boxer ever from Cincinnati is probably former heavyweight champion Ezzard Charles, who is regarded by many respected boxing historians as the top light heavyweight ever even though he never held a 175-pound title.

If it's not Charles, though, then it has to be the legendary

Dana White's job is to convince a public that has a myriad of attractive, and often cheaper, sources of entertainment on a Saturday night to buy a ticket or a pay-per-view for one of his fights.

The UFC president is as good at it as anyone who has ever lived, Tex Rickard, Don King and Bob Arum included.

Yet, no matter how good of a salesman White is, he's not going to be nearly as successful without his best product.

Imagine the bottom line at Coca-Cola if it weren't able to sell Coke for the next 18 ½ months. Apple's stock has dropped more than $150 in the last two months or so, but think of how much further it would plummet if it couldn't sell the iPhone next year.

That's the kind of position White has been in for the better part of the last year-and-a-half. Welterweight champion Georges St-Pierre, arguably his best fighter and unquestionably his biggest star, has been unable to compete. Two different knee injuries have kept St-Pierre on the sidelines since April 30,

LAS VEGAS – Mikey Garcia knocked Jonathan Barros out Saturday as viciously as you'll ever see, crushing the Argentinian with a left hook that Garcia seemed to start from his ankles.

Somehow, Barros managed to get up before referee Robert Byrd hit 10, but he was unable to continue and Garcia had a well-earned technical knockout win.

The crowd in the ballroom at the Wynn Resort went wild celebrating the finish after what had been a tentative, slow-paced fight most of the way.

One of the spectators at ringside, though, did little but sneer.

Orlando Salido, the WBO featherweight champion and one of the hardest-edged guys in the business, wasn't particularly impressed by the rising star's performance.

"He started very slowly and if he starts that way against me, he doesn't have the capability to beat me," Salido said. "That was a good left hand. It was a good punch he landed, and it's his signature punch, but [Barros] and I are different fighters. He won't do that to me."

The former Strikeforce champion countered a kick from Rich Franklin, landing an overhand right to the cheek that sent Franklin tumbling face first to the canvas and knocked him out cold.

Le didn't have to do another thing as referee Marc Godard dove in to stop it at 2:17 of the first round.

"I'm just grateful," Le said in the cage at the Cotai Arena in Macao, China, after one of the most dramatic knockouts of the year. "I don't know what to say. Lucky punch."

Franklin was an overwhelming favorite, in part because there was plenty of questions about the health of Le's right foot. He suffered a significant bone bruise during a win over Patrick Cote at UFC 148 in July and

NELLIS AIR FORCE BASE, Nev. – Ronda Rousey walked off an F-16 fighter jet after a wild one-hour ride over the Las Vegas desert and immediately bounced on her toes and threw a combination of punches in the air.

Clearly, the Strikeforce bantamweight champion was exhilarated by her ride with the Thunderbirds, though she wasn't so thrilled to talk about whether her next mixed martial arts fight will be in the UFC.

(Kevin Iole)Still wearing her Air Force jump suit, Rousey did what she called her "I-don't-know-anything dance" when she was asked whether she was aware of reports that Strikeforce would fold early next year and that she'd be in the UFC.

"Seriously?" she said when asked about the reports. "If anything were going to be released, do you think they'd do it through me on your iPhone in this hangar?"

The questions about her fight future were the only downers for the burgeoning superstar during a busy morning in Southern Nevada. She rode from Nellis to Creech Air Force base in a $30

LAS VEGAS – Mikey Garcia was in fourth or fifth grade when he suddenly became extraordinarily popular among his classmates. It was, however, for nothing he had done.

Garcia grew up in the boxing-mad community of Oxnard, Calif., and his older brother Robert had won a world super featherweight championship. Though Mikey had no desire to box, it made him something of a celebrity among his classmates.

(AP) "They'd all come up to me and ask me if I could get them an autograph or get them a picture [with Robert]," Garcia said, beaming. "My father [Eduardo] was training [ex-world champion] Fernando Vargas and they would ask me about them, too."

Vargas was a member of the 1996 U.S. Olympic team and quickly turned into a professional star. He won a world title in 1998 in just his 15th professional fight and was known for his fan-friendly style and close relationship with Eduardo Garcia.

Vargas considered Eduardo Garcia a father figure and, to this day, refers to him as "El Jefe." He'd stop

With Strikeforce set to fold, Ronda Rousey is set to invade the UFC (Getty Images)Multiple sources confirmed to Yahoo! Sports Thursday that Zuffa has reached a deal with Showtime to end the Strikeforce promotion sometime early in 2013, a move that will bring superstar Ronda Rousey into the UFC.

Neither UFC president Dana White nor UFC CEO Lorenzo Fertitta could be reached for comment on Strikeforce's demise, which was first reported Thursday by TMZ. Chris DeBlasio, a spokesman for Showtime, which has broadcast Strikeforce events since 2009, declined comment.

The plan is for the promotion to fold after a Jan. 12 card in Oklahoma City, in which all of the Strikeforce men's champions will defend their belts. A source stressed that nothing has been signed and, thus, things could change.

That, however, appears unlikely, given the frequently rocky relationship between White and Showtime officials. Folding the promotion into the UFC would also follow Zuffa's pattern.

Zuffa purchased Strikeforce from Silicon Valley Sports & Entertainment in March 2011, reportedly for more than $40 million. Given that Zuffa had previously purchased competitors PRIDE, World Fighting Alliance and World Extreme Cagefighting and merged them into the UFC, speculation mounted almost instantly about Strikeforce's future.

Strikeforce cards in September and November were canceled as the tensions between the sides heated.
