Malki Kawa, the agent for Melvin Guillard, posted on social media Thursday afternoon that “The Young Assassin” has been released from the World Series of Fighting.

Guillard (32-14-2) made it known that he was not happy with the WSOF recently after a loss to Justin Gaethje in which he missed weight. The promotion removed him from a planned fight earlier this year after they were unable to obtain medical information.

Guillard fought several times for the UFC, including 2012 fights against Jim Miller and Donald Cerrone.
