(Morgan Hancock/AAP PHOTOS)New Zealand's Joseph Parker will be back in the ring soon after serving his doping ban. Parker is free to fight again after the anti-doping organisation accepted "any ingestion of cocaine by Parker occurred out-of-competition only and in a context unrelated to sport performance." An independent scientific expert told UKAD he concluded "Parker administered cocaine out-of-competition" - meaning not the day of the competition. In June, UKAD said it confirmed to Parker that in light of the expert's opinion, it was satisfied any ingestion of cocaine occurred out-of-competition.
