UFC president Dana White says fast-rising light-heavyweight contender Jon Jones is undoubtedly one of the sport’s top prospects.

However, he also says that the UFC on Versus 2 headliner has some big tests to pass before he’s considered one of the sport’s best.

In our official event preview, MMAjunkie.com’s Steven Marrocco breaks down the latest test and why veteran opponent Vladimir Matyushenko thinks his years of experience could be the deciding factor in the Vesus-televised fight.

It’s been nearly 20 months since UFC middleweight Mike Massenzio stepped into the octagon.

After injuries and illness kept him away for so long, Massenzio surely feels the pressure going into his fight with former WEC champion Brian Stann on Sunday at UFC on Versus 2, right?

“I try not to think of it like that,” Massenzio recently told MMAjunkie.com. “I love to fight, and I love to be in the UFC.”

The main card for September’s WEC 51 event now appears complete.

World Extreme Cagefighting officials recently moved a featherweight bout between “The Korean Zombie,” Chan Sung Jung, and opponent George Roop from the preliminary card to the night’s Versus-televised main card.

The five-fight televised lineup is now set for the card, which takes place Sept. 30 at the 1STBANK Center in Broomfield, Colo.

The flow of massive wrestlers into mixed martial arts continues, and
former Oklahoma State Cowboy Jared Rosholt is the next heavyweight ready
to make the plunge.

Team Takedown boss Ted Ehrhardt revealed on Thursday to MMAjunkie.com Radio that Rosholt has joined brother Jake, WEC
lightweight contender Shane Roller, and UFC welterweight Johny Hendricks
on the Team Takedown roster.

“We have signed a new fighter – Jake’s brother, Jared Rosholt,” Ehrhardt
said. “He’s a three-time All-American, and he finished second in
nationals this year.”
