Reigning World Series of Boxing Champions Kazakhstan Astana Arlans host the British Lionhearts in the second leg of their semi-final on May 26th.
Kazakhstan carry a slender 3-2 advantage from the first leg in Sheffield. Wins for Galal Yafai and Cheavon Clarke, both Commonwealth Games medallists, were not enough at Ponds Forge International Sports Centre.
Hometown boxer Dalton Smith, who returned to international boxing after 18 injury-hit months, narrowly lost to Dilmurat Mizhitov. Niall Farrell and Jordan Reynolds also suffered points defeats.
This week, Will Cawley, Calum French, Carl Fail, Solomon Dacres represent the Lionhearts, alongside Sweden's Liridon Nuha.
Last year, Kazakhstan beat Britain at this stage before triumphing over Cuba, and now the Lionhearts once again face a tough task if they want to reach the final.
