Godolphin trainer Saeed bin Suroor is taking over a training licence at the doping scandal-hit Moulton Paddocks operation temporarily until a new trainer is appointed, the racing stable said on Thursday.
"The role is in addition to Saeed bin Suroor's responsibilities for horses based at Godolphin Stables in Newmarket," the stable said in a statement on its website.
"The test results for horses at Moulton Paddocks are still awaited and there will be no runners from there until they are all known," it added.
The British Horseracing Authority handed Godolphin trainer Mahmood al-Zarooni an eight-year ban for doping horses with anabolic steroids last month after 11 horses tested positive. He also admitted administering prohibited substances to four others.
Emirati Zarooni, who the BHA said personally brought anabolic steroids into Britain from Dubai, has appealed against the ban.
The scandal has caused serious embarrassment to Godolphin owner Sheikh Mohammed bin Rashid al-Maktoum, United Arab Emirates Prime Minister and Dubai ruler, who closed Moulton Paddocks and ordered the testing of all horses in Zarooni's care.
