In 1994 Dove-Edwin won a surprising silver medal in 100 metres at the Commonwealth Games, behind the expected winner Linford Christie but ahead of Michael Green and Frankie Fredericks, becoming the first medal winner in athletics for Sierra Leone. However, a few days later as Dove-Edwin prepared to run in the semi-final heat of the 4 x 100 metres relay event, he learned that the doping test sample he had delivered after the 100 metres final contained traces of the banned substance stanozolol. He was given a two-year ban by the IAAF and stripped of the medal, whereas Green was promoted to silver medallist and Fredericks to bronze medallist. Commenting on the suspension in retrospect in 2002, Dove-Edwin stated that he "was a victim of circumstances and a procedure that was full of flaws", and that he "never took steroids or anything".
