Undefeated world champion Keith Thurman sustained an injury as a result of a car accident that has forced his welterweight title defense date against Shawn Porter at Mohegan Sun Arena to be cancelled. The announcement was made yesterday by promoter Lou DiBella, president of DiBella Entertainment. According to his doctors, Thurman’s injuries are not considered serious and he is expected to be cleared to resume training in the coming weeks. Thurman vs. Porter was the main event of a scheduled two-fight card to be broadcast in prime time on CBS on March 12th. This fight and the network broadcast will now be rescheduled for a later date.
