Hannah Sue Burnett, The Plains, Va., has withdrawn Jacqueline Mars’ Harbour Pilot from the Land Rover Burghley Horse Trials. The Karen E. Stives High Performance Eventing Grant recipient had a brilliant round over Capt. Mark Phillips cross-country track on Saturday to rise to seventh place by collecting only 13.2 time faults.

Due to concern over a minor injury, Burnett, in consultation with the team veterinarian and U.S. Eventing Chef d’Equipe David O’Connor, has decided it’s in the best interest of the 11-year-old Irish Sport Horse gelding not to contest the show jumping phase this afternoon, and save him for another day.

“After a stellar performance yesterday, we have sadly had to withdraw ‘William’ from the rest of competition due to a concern to his soundness,” wrote Burnett on her Facebook page. “We are confident that he will be OK, but William’s well being is of utmost importance to me and my wonderful team. Thank you for the tremendous support. I’m so proud of my horse and my team this week.”

Great Britain’s Sophie Jenman also withdrew Geronimo before the final horse inspection, and Roo Fox’s Fleet Street was eliminated at the last jog. 

Two Americans remain in contention at Burghley, Allison Springer on Arthur, who stands 20th after cross-country, and Marilyn Little on RF Demeter, who stands 24th.
