He next made his debut against Jacob Volkmann, losing a close decision. He was afterwards surprisingly cut by the UFC. He was next set to defend his MFC title against Drew Fickett. He pulled out a few weeks before the bout and was replaced by Matt Veach.
McKee then vacated the title and gave it up for grabs in a match between Fickett and UFC veteran Hermes Franca. He was next set to make his Dream debut in a non-title bout versus current lightweight champion Shinya Aoki. Unfortunately McKee was forced to drop out of the fight due to visa issues. He was replaced with UFC veteran Shane Nelson, who stepped up on very short notice.
McKee recently re-signed with MFC and he was next set to defend his reclaimed MFC lightweight title against new contender and fellow UFC veteran Brian Cobb. McKee accepted another matchup in Australia in the meantime against the Aussie Jai Bradney. He defeated Bradney via first-round submission.
After the victory over Bradney, McKee came in seven pounds overweight against Cobb and he was stripped of the MFC lightweight title and he was also informed that he would be fired from the MFC roster after the Cobb fight, win lose or draw. McKee won his final MFC fight via a less-than-entrancing unanimous decision.
McKee next faced Chad Dietmeyer winning a -- you guessed it -- unanimous decision. McKee next signed to make his Dream debut once again, against current lightweight champion Shinya Aoki. Aoki defeated McKee via second round submission due to a punch over McKee's eye.
After a decent layoff, McKee is next set to make his WSOF debut against Lewis Gonzales.
