The GB team will complete a record six medals at Tokyo 2020, but Clarke’s welfare story has come to an end against his rival from Uzbekistan.
Clarke had forced a permanent reckoning on her birthday opponent, but her Olympics ended with a terrible cut above her eye that was originally sustained in her previous fight.
The referee ended this semi-final in the third round due to the cup – Jalolov won.
Clarke was quickly forced into the back foot by Jalolov’s left hands pulled from his left-handed position.
Jalolov ended up mixing up the right brackets.
Clarke responded with a right hand, her best moment so far, with the last punch of the first round.
Out of nowhere, Clarke hit home a right hand in the second round, which forced Jalolov to count by the referee. Jalolov insisted he had slipped but it was a huge moment of encouragement for the Briton.
Clarke put on the pressure but ended the round bleeding from a cut above his own eye – the same head-butt injury he suffered when he won his quarter-final two days ago.
The referee saw the cut in the third round and ended the fight early in favor of Jalolov.
For Clarke, it was a courageous end to a sensational journey.
Qualifying for Tokyo 2020 was his third attempt to reach the Games – he had previously been turned down by Anthony Joshua (who won gold in 2012) and then Joe Joyce (silver in 2016).
Clarke, 29, had worked as a security guard and was stabbed before renewed maturity saw him finally reach the Olympics after 12 years on the GB team.
He joins Karriss Artingstall as a bronze medalist.
Pat McCormack and Ben Whittaker won silver medals.
Galal Yafai at flyweight and Lauren Price at middleweight are expected to compete in the semi-finals.
Jalolov will fight for the gold medal on Sunday against American Richard Torrez Jr, who won his semi-final with a third-round stoppage against Kazakh Kamshybek Kunkabayev.
