Felix Sturm missed out on becoming the first German to win five world titles after his points defeat to Russia's Fedor Chudinov in Frankfurt on Saturday for the vacant World Boxing Association (WBA) super middleweight title.

The 36-year-old Sturm had been fighting for Carl Froch's former title, after the WBA stripped the British fighter of his belt for inactivity a week ago.

It was the fifth defeat of Sturm's career following 18 knockouts in 39 victories having stepped up from middleweight.
