Recently, UFC heavyweight and fan favorite Mark Hunt made headlines for filing a civil suit against the UFC, Dana White, and Brock Lesnar, alleging racketeering, fraud, breach of contract, and negligence among eight charges surrounding his fight with Brock Lesnar at UFC 200.
Lesnar made his return to the UFC after a four and a half year retirement but the short notice nature of his return led to him receiving an exemption from the UFC from the full four month USADA testing before competition. Instead Lesnar was only tested for a month before the fight.
