 In the third round, Katsidis continued to charge at Mitchell and was soon able to land a combination of hooks which made the latter stumble backwards on unsteady legs.From thereon, Mitchell was unable to fully regain his composure and, less than two minutes later, he was buckled by a hard left hook and a further succession of unanswered punches, at which point referee Dave Parris stopped the fight.Immediately after the Mitchell bout, the WBO mandated that Juan Manuel Márquez must face Katsidis for the 'full' version of the lightweight world championship, or risk being stripped.
