Marion Jones is expected to plead guilty on Friday to using steroids in the build-up to the 2000 Olympic games.

US Track and Field chief executive officer Craig Masback has expressed his disappointment in Justin Gatlin after the world and Olympic 100 metres champion was banned for a maximum of eight years after admitting his positive test “constituted a doping violation”.

Former world record holder Tim Montgomery has been stripped of his American 100 metres record following his two-year drug suspension handed down by the Court of Arbitration.
