UFC's pound-for-pound king returns on April 26th in the main event of UFC 172 in Baltimore. UFC light heavyweight champion Jon "Bones" Jones defends his title for the seventh time against Brazilian powerhouse Glover Teixeira. Jones has defeated an impressive list of opponents since becoming the youngest champion in UFC history in 2011, but in the veteran Teixeira, he will face a dangerous challenger who hasn't lost in nearly nine years.
