An LA-based boxer is suing Jay-Z and Roc Nation Sports after suffering a traumatic brain injury in the ring. According to reports, Daniel Franco signed a four-year contract with Roc Nation Sports in 2015 with seven knockouts under his belt. According to Franco, he was unable to prepare for a fight against Christopher Martin in March of 2017 due to the flu, and when he tried to get out of the bout, Roc Nation told him to proceed or face “difficulty securing future fights.”
