Roller lost via submission at 2:38 of the first round, his fourth defeat in his last five bouts
The UFC lightweight was a three-time collegiate All-American wrestler at Oklahoma State University who transitioned into MMA as part of Team Takedown, a group of decorated former amateur wrestlers that included Johny Hendricks and Jake Rosholt.
The 33-year-old Roller had an inconsistent career that spanned just over five years. He was signed to the Zuffa-owned WEC within just over one year of his MMA debut and won his first two fights there until losing to Ben Henderson. He also owns victories over respected veterans like Jamie Varner, Danny Castillo and Thiago Tavares.
With his UFC on FX 5 defeat, he ends his career with a record of 11-7.
