Ohuruogu's ban expires on 6 August in time for the Worlds

The 400m runner, whose ban for missing three drugs tests expires on 6 August, lodged an appeal with the British Olympic Association (BOA) last month.

Triathlete Tim Don successfully had his ban for missing drugs tests overturned by a BOA Appeals Panel in May because of "mitigating circumstances".

Ohuruogu's lawyers will argue a similar case in the hope of winning an appeal.

Ohuruogu could find circumstances in her favour as the BOA is considering lightening punishments for athletes who miss drugs tests.

A BOA spokesperson said Don's case "could be positive for her", but stressed that it did not set a precedent.

UK Athletics performance director Dave Collins, however, remains hopeful a similar exception will be made for Ohuruogu.

He said: "I'd be hopeful, given the decision the BOA have given recently."
