The UFC is live in Pittsburgh, PA for the fourth edition of UFC Live on Versus and will now feature a new main event following news that Nate Marquardt had failed his medicals, which subsequently led to him being fired by UFC President Dana White.

Pat Barry and Cheick Kongo will headline the card while Rick Story, who had originally been scheduled to face Marquardt in the main event, will now face Charlie Brenneman. Matt Mitirone also looks to keep his undefeated streak alive inside the UFC Octagon clashing with Christian Morecraft in heavyweight action.

We have complete main card results of the live show on Versus below and you can check out results from the preliminary fights that aired live on Facebook earlier in the evening after the jump.
