===Final world title shot===
{{Main article|David Haye vs. John Ruiz}}
After petitioning the WBA to protest against the outcome of his controversial fight with Valuev, Ruiz was made the WBA's mandatory challenger to fight the winner of Chagaev-Valuev II in 2009. As that bout was cancelled, Ruiz stepped aside as mandatory challenger so Valuev could fight Cruiserweight Champion [[David Haye]]. On the undercard to that fight Ruiz stopped Adnan Serin in 7 rounds. Ruiz, coming in at 226 pounds (his lightest since 2001), dominated his overmatched opponent to retain his mandatory challenge to the WBA belt. Valuev later lost a majority decision to David Haye, meaning Ruiz would now fight Haye for the WBA title, after Haye had recovered from a hand injury. When the fight took place on April 3, 2010 at the [[Manchester Arena|M.E.N. Arena]] in [[Manchester]], Ruiz lost to Haye by TKO when his corner threw in the towel in the ninth round after suffering four knockdowns in the previous rounds. Ruiz, whose face was covered in blood, could not stand up to Haye's greater speed and power.
