The player retention window for The Hundred 2027 tournament is officially open, allowing the eight men's and women's teams to secure players from their 2026 squads. This window began on October 19, 2026, and will close on January 15, 2027. During this period, teams can announce retained players at any time.

Key details include:

• Each squad can retain up to 16 players from the 2026 season.
• Retained players will maintain their 2026 salaries for the upcoming season.
• Teams can retain any player from the 2026 Auction, including those who did not participate due to injury or unavailability, as well as replacement players who played at least two games.

For players not retained, they remain eligible for signing during the direct signing window from January 20 to February 3, 2027, or they may enter the auction in March.

A significant change for 2027 is the increase in squad size and overseas player limits:

• Teams can now carry a maximum of 19 players (up from 16).
• The number of overseas players allowed in a squad has risen from four to five, with four permitted in the playing XI (up from three).
• This additional overseas player can be utilized at the team's discretion.

The Hundred Auction is scheduled for early March 2027, with the exact date to be confirmed. These changes aim to enhance the competitive landscape of the tournament.
