The report was first confirmed by TMZ.com.
Pearson is currently in Las Vegas assisting teammate Dominick Cruz as an assistant coach on the latest season of The Ultimate Fighter.
According to the report, Pearson was pulled over by police after his car was seen swerving on the road. Police stopped the British born featherweight and administered a field sobriety test, which he apparently failed as he was placed under arrest.
Pearson was taken to jail and booked on suspicion of DUI before being released later that day.
Pearson has yet to make a comment about the charge or subsequent arrest.
