Somerset's Ben Green, who finished second in the wicket-taking charts in the T20 Blast, will replace Ollie Pope at Welsh Fire while Ben Raine, Ish Sodhi, Jimmy Neesham and Mitchell Santner have also picked up contracts
A raft of replacement signings have been confirmed for the Men's Hundred, with Dan Worrall replacing Olly Stone at London Spirit.
Stone, who was picked up for £100,000 during March's draft, withdrew from the competition earlier this week due to a hamstring injury.
Though Australian born, Worrall, who has taken 56 wickets in 69 T20 appearances, qualifies as a local player due to his UK passport.
Somerset bowler Ben Green has been signed by Welsh Fire to replace Ollie Pope, who dislocated his shoulder during the second Ashes Test. Green collected 30 wickets – the second-most in the competition – and scored 183 runs at a strike rate of 142.96 as Somerset lifted the T20 Blast.

Elsewhere, defending champions Trent Rockets will lose the services of Rashid Khan from August 10, with New Zealand spinner Ish Sodhi picked up as a replacement signing.
Birmingham Phoenix have brought in Australian spinner Tanveer Sangha as a partial replacement for Shadab Khan. The Pakistan allrounder will be available for Phoenix's first five matches before heading to the Asia Cup, with Sangha joining up with the squad on August 14.
Ben Raine, who picked up 16 wickets with an economy of 7 for Durham in the T20 Blast, has replaced injured Kent and Netherlands quick Fred Klaassen at Manchester Originals while Zaman Khan will deputise for Josh Little when the Ireland bowler is away on international duty.
Little will miss the Originals' matches against Northern Superchargers (August 20) and Southern Brave (August 23) but will be available for the knockout stages if they finish inside the top three.
Jimmy Neesham will don Oval Invincibles turquoise from August 20, replacing Heinrich Klaasen, while fellow New Zealander Mitchell Santner is tasked with filling Tim David's shoes at Southern Brave for their final group match and the knockout stages (qualification permitting).
