This has to be the oddest way to quickly end an MMA fight. Marlon Moraes kicks Joe Barajas behind the knee and Barajas just goes down. If you watch the video below, it seems like Moraes barely makes contact with the kick. Either this kick has wicked power or it was a phantom ghost and Barajas actually suffered some other sort of leg injury unrelated to the kick. Maybe the guy pulled a hamstring?
