UFC lightweight and former WEC standout Shane Roller has called it quits today following his loss this past Friday night (Oct. 5, 2012) on the UFC on FX 5 preliminary card.

News of the retirement actually came from Roller himself who made the announcement via his Twitter account at about 3 p.m. ET.

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

The announcement comes on the heels of a first round submission loss to Jacob Volkmann via rear naked choke. With the defeat, Roller had lost a total of four of his last five bouts with his only victory being a unanimous decision over John Alessio at UFC 148 in July.

The Team Takedown fighter was likely in severe jeopardy of being released from the Ultimate Fighting Championships following his recent performance, one which he publicly admitted was extremely frustrating in the immediately fallout of the loss:

"By far the worst fight of my career. I was in great shape & ready, just didn't do a damn thing out there tonight. Off night 2 say the least"

Roller finishes his professional MMA career with a record of 11-7. He held a 6-2 record during his solid run in the WEC and a 2-4 record during his stint with the UFC. His WEC run was particularly impressive, earning victories over current UFC lightweights Jamie Varner, Anthony Njokuani and Danny Castillo.

At 33 years old, Roller has plenty of time to get that next chapter started.
