Brazilian Jose Aldo successfully defended his featherweight crown with a fourth round technical knockout of Chan Sung Jung on Saturday night at UFC 163 in Rio Di Janeiro.

Padding his resume as one of the best pound-for-pound scrappers in the world, Aldo completed his fifth consecutive title defense by taking advantage of the “Korean Zombie’s” dislocated left shoulder in the fourth. As Sung tried to come over the top with a right hook, Aldo swung with his left and the two locked arms, causing the South Korean national to separate his shoulder.

Jung tried to fight through the pain and pop his shoulder back into place, but Aldo (23-1) proceeded to pounce and forced the TKO.

Aldo was originally supposed to fight Anthony Pettis, but a knee injury kept him out and put Jung in line for the title.

The 26-year-old Aldo was in control for most of the match, but won largely with his unexpected takedowns. It was believed the more submission-minded Jung (13-4) would be the first to go to the mat, but Aldo consistently brought his opponent down while providing some of his patented flying knees. Overall he completed five of his six take down attempts and 32 of 87 strikes, while Jung managed 17 of 117 strikes.
