Since the early days when the sport was anything but a mainstream endeavor, the MMA industry has thrived and survived through various websites, forums, and – perhaps most importantly – social-media platforms. Fighters interact with fans, each other and many more through the likes of Twitter, X, Facebook and Instagram, which helps outsiders get a deeper look into the minds of the athletes. Following Saturday’s UFC on ESPN 50 in Nashville, Tenn., several of the winning and losing fighters, along with their coaches, training partners or family members, took to social media to react to the event or share a message with supporters.
