For the first time in UFC history, back-to-back main events have ended with a “TKO due to injury” designation. First, it was UFC on ABC 3, where Brian Ortega suffered a shoulder injury upon his escape from a Yair Rodriguez submission attempt. One week later, Tom Aspinall suffered a knee injury that ended his UFC Fight Night 208 main event vs. Curtis Blaydes in premature fashion. While the term “freak injury” might not be appropriate to use when discussing a sport that is inherently dangerous, 13 have ended in unforeseen injuries – broken legs, separated shoulders, eye pokes, etc
