The Basic Rule: Four Overseas Players Per Side
As a former coach who has spent plenty of time navigating squad regulations, I can tell you that player eligibility rules are rarely as straightforward as they look on paper — and The Hundred is no exception. The headline rule is simple enough: each franchise is permitted to field a maximum of four overseas players in any given match, and squads cannot carry more than four overseas-contracted players at any one time. It is a clean cap designed to protect opportunities for homegrown talent while still allowing the tournament to attract world-class names from abroad.
From a betting perspective, the overseas allocation is worth tracking closely. Franchises that are forced to rotate their overseas spots due to international call-ups or injury can see their outright odds shift noticeably, particularly mid-tournament when form is already established.
When Things Get Complicated: The London Spirit Case
The rule came under scrutiny during a men's match this season when London Spirit lined up against MI London with five players who were born outside the United Kingdom. At first glance, that looks like a clear breach. In practice, it was entirely within the regulations, and understanding why tells you almost everything you need to know about how eligibility actually works in this competition.
Spirit's four designated overseas players — Adam Zampa, Dewald Brevis, Adam Milne, and Lhuan-dre Pretorius — all took their places as expected. The fifth man in question was Australian pace bowler Andrew Tye, who at 39 years old has represented Australia on 39 occasions across one-day and T20 international cricket. Despite that international pedigree, Tye does not occupy an overseas slot at Spirit. When he joined earlier this season as a replacement for Adam Hose, he did so on a domestic contract, made possible by family ties to the United Kingdom.
Passports, Family Links, and Domestic Eligibility
Tye is far from alone in qualifying as a domestic player despite a prominent international career elsewhere. Mohammad Amir, the seasoned Pakistan left-armer with 159 international appearances across all three formats, is part of the Trent Rockets setup this season — and he too counts as domestic. Because his wife is a British citizen, Amir holds a British passport, which removes the need for an overseas slot entirely.
A further example is Dan Worrall, who has represented Australia in three one-day internationals. Worrall featured for London Spirit during the 2024 and 2025 seasons without taking up an overseas berth, again courtesy of British passport eligibility. The pattern here is clear: it is nationality and passport status, rather than international cricket history, that determines which category a player falls into.
What This Means for Franchises and Fans
From a squad-building standpoint, identifying players with international experience who nonetheless qualify as domestic signings is a genuine competitive advantage. Franchises that can add proven overseas-standard talent without burning one of their four slots are effectively getting something for nothing, and it is a recruitment edge that the shrewder team managements have clearly cottoned on to.
For supporters watching at home or following the markets, it is worth keeping tabs on which players in each squad hold British passports or have family connections to the UK. A team that appears light on international firepower on paper might actually have considerably more depth than the overseas column suggests. In a competition as fast-moving as The Hundred, those details can make all the difference.
