Jack Marton struggled to make any impact as his Tokyo Olympics campaign ended in a heavy round-of-16 loss in the men's 85kg Taekwondo class.

The 12th-seeded Marton from Melbourne was no match for Egypt's Seif Eissa, going down 11-1 at Makuhari Messe Hall on Monday.

The fifth seed was up 8-0 less than a minute into the contest thanks to a pair of kicks to the head and another to the body.

The contest was a good as over after the first round as the Egyptian held a 11-0 lead, with Marton's sole point coming from a penalty to Eissa.
