He is most notable for his 21 fight tenure in the Ultimate Fighting Championship (UFC) between 2012 and 2023, where he competed in the Middleweight division. Brunson made his professional MMA debut in May 2010 against John Bryant where he won by a rear-naked choke in under a minute. He then won his next five fights with none of them making it past 2:30 of the first round. Brunson made his Strikeforce debut on June 24, 2011, at Strikeforce Challengers: Fedor vs. Terry against undefeated Jeremy Hamilton. He won the fight via unanimous decision.
In a quick turnaround, Brunson fought his second fight for Strikeforce just over one month after his debut. He faced Lumumba Sayers on the undercard of Strikeforce: Fedor vs. Henderson on July 30, 2011. He won the fight via submission in the first round.

He was scheduled to face Ronaldo Souza on March 3, 2012, at Strikeforce: Tate vs. Rousey. However, the Ohio State Athletic Commission denied his fight license based on an eye exam he had submitted. Brunson fought wearing contacts in all of his bouts, but Ohio has a rule against this. He immediately scheduled a Lasik procedure and missed about six weeks. He later faced Souza on August 18, 2012, at Strikeforce: Rousey vs. Kaufman and was defeated by KO at :41 of the 1st round.[16]
