2016 silver medallist Matthew Glaetzer was on target for his second career men’s sprint podium appearance before unceremoniously exiting the competition after being relegated by event officials following his quarterfinals match up.

To most inside the Hong Kong Velodrome, it appeared Glaetzer had moved through to his third semi final in four years after edging New Zealand’s Ethan Mitchell with a strong ride in the third and deciding heat.

However in a decision that not just puzzled Glaetzer and Australian team management, the result was overturned after officials deemed the Australian to have made ‘an irregular movement which prevented Mitchell from passing’ inside the final lap of their contest.

The ruling meant Mitchell moved through to the semi final.

Earlier in the competition, the powerful South Australian who finished fourth at the Rio 2016 Games, began his assault on the title with the fifth fastest qualifying time on Friday (9.815).

He then cruised into Saturday’s quarter-finals with two strong rides over Colombia’s Santiago Ramirez Morales and Russia’s Pavel Yakushevskiy.

The premature end to Glaetzer’s 2017 campaign left the dual Olympian with three top six placings after he narrowly missed Thursday’s keirin podium (fourth) and grabbed sixth on the opening day in the team sprint.

Also for Australia in the sprint, reigning national champion Patrick Constable, 21, clocked 9.975secs to move through Friday’s qualifying round before defeating Fabian Zapata (COL) in the round of 1/16.

However the might of four-time world championship sprint medallist Denis Dmitriev was too much for rising star Constable as his campaign ended to the Russian in the round 1/8.
