Overview

• Arran Gulliver tested positive for the banned anabolic agent ostarine in March during training for the Lake Placid world championships.
• He accepted the ITA ruling and is ineligible through March 23, 2027, with all results from March 2, 2025 disqualified, including his 2025 worlds finish.
• The International Bobsleigh & Skeleton Federation is responsible for any medal reallocations, which could elevate the U.S. four-man team to bronze.
• The ITA said the violation was not intentional, and the case can be appealed by WADA or UK Anti‑Doping, with the possibility of a longer sanction.
• The British Bobsleigh & Skeleton Association said it fully supports the decision, while Gulliver stated a contaminated supplement led to the positive test.
