TMZ first reported the news.
In Las Vegas to assist teammate Dominick Cruz in coaching The Ultimate Fighter: Live, Pearson was pulled over somewhere around 4AM on Sunday morning, April 29. The 27-year-old was pulled off the road for allegedly swerving his vehicle. Law enforcement administered a field sobriety test and, based on the outcome, placed Pearson under arrest on suspicion of DUI.
Winner of The Ultimate Fighter 9, Pearson has competed seven times in the octagon, amassing a 5-2 record; his only losses in the promotion have come against Cole Miller (submission) and Edson Barboza (split decision). Following the defeat to Barboza, Pearson headed south to featherweight. He made his debut at 145lbs this past December at UFC 141, where he earned a unanimous decision over Junior Assuncao.
The British fighter is expected to face Cub Swanson at UFC on FX 4 this June 22. No word yet on how or if this arrest will affect the bout.
