Today, the Utah native is without a job.
The 30-year old Johnson announced via Twitter on Tuesday that he had been cut from the UFC roster, tweeting "And the hits keep on coming ... no longer a UFC fighter."
Johnson (16-12) has been fighting since 2005 and was with the UFC since "The Ultimate Fighter 9," where he lost the welterweight finale to James Wilks.
After the loss to Wilks, he won three out of his next four fights, but then the trend turned downward, as he dropped four out of his past five.
Johnson suffered a bad knockout at Swick's hands at UFC on Fox 4 on Aug. 4 in Los Angeles, but agreed to fight Gunnar Nelson at a catchweight of 175 on short notice (replacing Pascal Krauss) at UFC on Fuel 5. Johnson missed the catchweight by eight pounds, then lost to Nelson via first-round submission.
