10 of the worst injuries in MMA history

#7 Rousimar Palhares vs. Mike Pierce

UFC On FX: Sotiropoulos v Pearson

The Brazillian Palhares fought Pierce back in 2013 which was termed as the battle between two great submission artists. Palhares was infamous for holding onto his submissions for too long. The free-flowing fight took a nasty turn when Palhares caughtPierce's leg in a tight lock.

Pierce almost tapped immediately but Palhares didn't let go of his foot. The ref tried to pull him apart but he continued latched onto pierce's leg. Finally, he let go of Pierce's leg which was messed up pretty bad by then. Branded as one of the cheapest moves in history, Pierce returned from the injury one last time against Ryan LaFlare and hasn't fought ever since.
