Perth have axed star Big Bash League import Laurie Evans after last year's player of the final tested positive to a banned substance in England.
The English batter, who was Perth's first draft pick as a retention player, revealed overnight he had failed a test during the northern hemisphere summer.
The 35-year-old T20 specialist insisted in a statement he did not know what caused the positive reading, adamant he had not taken any banned substance.
