Shane Roller Retires Following Loss To Jacob Volkmann At 'UFC On FX 5'

At 33-years-old, five-year veteran Shane Roller (11-7) has announced his retirement from mixed martial arts. 

The WEC and UFC vet announced his departure from the sport via Twitter on Monday.

"Looks like I'm hanging up the gloves for good," Roller tweeted. "It was fun, but time to move on. Sux that it ended like that. Now startin the next chapter!!"

The announcement comes just two days after a first-round submission defeat at the hands of Jacob Volkmann at last weekend's UFC on FX 5. The loss marked his fourth in five outings.

After joining the WEC in 2008, Roller went on to notch notable wins over Danny Castillo, Anthony Njokuani and Jamie Varner. His UFC debut would come three years later where he would score a second-round KO over Thiago Tavares.

Following the impressive win over Tavares, however, Roller suffered three consecutive losses to Melvin Guillard, T.J. Grant and Michael Johnson respectively. A win over John Alessio last July would snap the skid, though, Volkmann would soon hand the Oklahoma native another loss.
