His attempts to regain his World Championships decathlon title were thwarted by a hamstring injury in June 2009. This caused him to drop out of the US trials; thus, he missed the chance to compete at the 2009 World Championships in Berlin. He returned to action in 2010 and won the men's heptathlon at the 2010 IAAF World Indoor Championships. At the start of his outdoor season he won the 2010 Hypo-Meeting, holding off the challenge from Romain Barras.
