US Equestrian on August 1 announced a substitution for the Defender U.S. Eventing Squad ahead of the 2026 FEI Eventing World Championships. This update comes about one month after the initial team announcement on July 6. Phillip Dutton (West Grove, Pa.) has formally withdrawn Possante, who will now be replaced by Dutton’s other mount, Denim. Dutton said on social media that Possante, a 2013 KWPN gelding (Namelus R x Wendelien, by Otangelo) owned by The Possante Group, sustained an injury during training and won’t be healed in time for the World Championships in less than two weeks.
The Defender U.S. Eventing Squad for the 2026 FEI Eventing World Championships will now include the following combinations.

Will Coleman (Ocala, Fla.) and Diabolo, a 2012 Holsteiner gelding (Diarado x Roulett M, by Aljano 2) owned by the Diabolo Group, and cared for by Erin Jarboe
Direct Reserves: Off The Record, a 2009 Irish Sport Horse gelding (VDL Arkansas x Drumagoland Bay, by ARD Ohio) owned by the Off The Record Syndicate, and Very Dignified, a 2015 Irish Sport Horse mare (Dignified Van’t Zorgvliet x Katey’s Gem, by Ricardo Z) owned by Jerome Broussard, Gloria Callen, and Elizabeth Lendrum, both cared for by Erin Jarboe
