Leben returns at year-end show
UFC middleweight Chris Leben is returning to action after a suspension for a failed drug test.
UFC officials announced the bout on Wednesday.
Leben was suspended by the UFC in November of 2011 following a positive text for oxycodone and oxymorphone. The positive test came after his loss to Mark Munoz in England.
Meanwhile, Vemola last competed at "UFC on FUEL TV 4," losing to Francis Carmont. He is 1-1 as a middleweight in the UFC.
