null: A former world title challenger with dynamite in his fists and a world-class wrestling attack to lean on if he needs it, Josh Koscheck is back in the Octagon for the first time since a 2013 loss to Tyron Woodley, and this seasoned vet is more determined than ever to get back on the right track and make a title run. A near mirror image of Koscheck in terms of punching power and wrestling ability, Nebraska's Jake Ellenberger wants to set himself apart by halting his opponent's comeback in its tracks and making a statement that in 2015, 'The Juggernaut' will not be stopped.
