The riders were both suspended after their horses Clifton Promise and Clifton Pinot, tested positive for the banned substance reserpine at Burghley Horse Trials last September.
In a statement the FEI said:
“The FEI Tribunal has today lifted the provisional suspensions of Jonathan Paget (NZL) and Kevin McNab (AUS) with immediate effect. The 2 athletes had been provisionally suspended following positive tests on their horses, Clifton Promise and Clifton Pinot, for the banned substance Reserpine at Burghley (GBR) in September 2013.
“The decision follows a specific request from the 2 athletes for the lifting of the provisional suspensions. The request was made during a 2-day hearing before the FEI Tribunal in London (GBR) on 3-4 June.
“The lifting of the provisional suspensions is a preliminary decision. The FEI Tribunal’s final decision in both cases will be issued at a later date.”
