UFC Live: Jones vs. Matyushenko (also known as UFC on Versus 2) was a mixed martial arts event held by the Ultimate Fighting Championship on Sunday, August 1, 2010, at the San Diego Sports Arena in San Diego, California.^[2]

The event was initially scheduled to take place at the EnergySolutions Arena in Salt Lake City, Utah.^[3] On June 14, 2010, the promotion decided to move the event to a different venue and location due to low ticket sales.^[4] The event was the second UFC event to be broadcast on Versus; the first being UFC Live: Vera vs. Jones.^[3]

Jim Miller and Gleison Tibau were set to fight at this event, but the bout was later moved to UFC Fight Night: Marquardt vs. Palhares the following month.^[5]

Two bouts were moved to this event due to visa issues; Paul Kelly vs. Jacob Volkmann from UFC 116^[6] and Darren Elkins vs. Charles Oliveira from The Ultimate Fighter 11 Finale.^[7]

Joe Stevenson suffered a knee injury in training and was unable to fight Takanori Gomi. Stevenson was replaced by Tyson Griffin.^[8]

Willamy Freire also suffered an injury in training, forcing the cancellation of his fight with Thiago Tavares. Tavares was then pulled from the card altogether.^[9][10]

"Big" John McCarthy was a referee at this event, the first time he has refereed at a UFC event in almost 3 years.^[11]

Damarques Johnson originally weighed in at 172.5 pounds, 1.5 pounds over the contracted weight limit. After being granted one hour to make the original 171 pound limit, Johnson tipped the scales at 172 pounds. As a result, Johnson forfeited 20% of his purse for the fight.^[12]

The event drew an estimated 991,000 viewers on Versus.^[13]
