Before the main event of UFC 148 started Anderson Silva clearly wiped his hands over the legally applied vaseline on his face, and then proceeded to wipe his chest with it to help keep Sonnen off of him in takedown attempts. The ref Yves Lavigne saw it and wiped what he could off of him.
Silva was also guilty of holding the shorts on a few occasions that caused him to land punches on a vulnerable Sonnen. Eventually ‘The Spider’ won via TKO and had his hand raised and the belt placed around on his waist by the UFC President Dana White. Silva did try to cheat and may have marred his legacy with the win.
