Perhaps Ultimate Fighting Championship (UFC) Featherweight fighter Ross Pearson (13-5) didn't take the news to well that he had been passed over in favor of Erik Koch for a title shot against 145-pound kingpin Jose Aldo this summer.

"Real Deal" -- who unsuccessfully volunteered to challenge "Scarface" at UFC 149 later this year -- was arrested over the weekend in Las Vegas, Nevada, on suspicion of driving under the influence (DUI). The Ultimate Fighter (TUF) 9 Lightweight winner was pulled over at 4 a.m. Sunday morning and performed "miserably" on a field sobriety test, according to TMZ.com.

He was booked and then released most likely as soon as his buzz subsided. He is innocent until proven guilty.

Pearson was lined up to fight Cub Swanson next at UFC on FX 4 at the Revel Hotel and Casino in Atlantic City, N.J., on Sat., June 12, 2012. There's no telling if this latest incident will have any impact on that appearance at this time.

The British fighter recently shed 10 pounds after dropping two out of three fights at Lightweight, hoping he'd find better luck in the 145-pound division. His first test against Raphael Assuncao proved to be a difficult one, but one he passed via gritty unanimous decision win at UFC 141 last December.
