From USA Gymnastics:

Danell Leyva of Miami/Team Hilton HHonors (Universal Gymnastics), has withdrawn from the 2013 Men’s World Championships Team, which was named yesterday following the conclusion of the 2013 P&G Gymnastics Championships.  Leyva, who is recovering from a shoulder injury and has not been able to fully train, stated in his withdrawal letter, “I very much appreciate the opportunity to be, once again, part of the team that will go onto the world stage and represent the United States in the great sport that is gymnastics.  Unfortunately, I have to decline. … We have decided that the right decision for me, to better help the team in the future, is to retract from this competition so that I can heal further and reach my full potential yet again.”
