Calvin Harrison is to replace Usama Mir at Manchester Originals with immediate effect, after the Pakistan international was called up for his country.
The all-rounder made six appearances for the Originals over the last two editions of The Hundred, with best figures of 2/18 and a high score of 23.
Harrison's Metro Bank One Day Cup campaign has yielded three wickets, with a top score of 41 in Notts Outlaws' defeat at Radlett.
The leg-spinner will now join up with the Originals ahead of their final two matches, at home to Northern Superchargers (Sunday 20 August) and Southern Brave (Wednesday 23 August).
The Originals' men currently occupy the final qualification spot for The Hundred's knockout stages, which take place over the weekend of Saturday 26 and Sunday 27 August in London.
