A light-heavyweight bout between up-and-comer Jon Jones (10-1 MMA, 4-1 UFC) and veteran fighter Vladimir Matyushenko (24-4 MMA, 5-2 UFC) is official for August's UFC on Versus 2 event.

MMAjunkie.com (www.mmajunkie.com) passed along news of the bout this past week, and Matyushenko recently confirmed the fight as official on The Underground forum.

UFC on Versus 2, the second of two 2010 UFC events contracted to air on Versus, takes place Aug. 1 at EnergySolutions Arena in Salt Lake City.

Jones headlines his second UFC on Versus card. In the first, which took place in March, Jones dismantled opponent Brandon Vera with a stunning ground-and-pound attack that ended the fight in the first round.

The fight was Jones' first since suffering the only loss of his career, which was a controversial disqualification defeat in December. Jones appeared to earn a TKO win over Matt Hamill. Replays showed the elbows Jones used to earn the victory were illegal, and Hamill, who was already dazed before the strikes, was awarded the dubious victory.

Matyushenko returns to competition after a split-decision win over Eliot Marshall, which also took place at UFC on Versus 1. The 39-year-old Matyushenko is currently 2-0 in his return to the UFC after earning a 3-2 mark in the octagon in a stint from 2001 to 2003. The former IFL light-heavyweight champion now has won 11 of his past 12 fights.
