Brook was fined and warned about his future conduct by the England and Wales Cricket Board (ECB) following the incident, which occurred the night before a one-day international.
He expressed relief at retaining his captaincy, stating he informed the ECB of the event mid-game, which he believes saved him from more severe punishment.
The incident contributed to broader concerns about England's "drinking culture" during the troubled Ashes series, prompting an ECB review into player behaviour.
As a result, new restrictions, including a midnight curfew, have been agreed upon for the team's upcoming tour of Sri Lanka and the T20 World Cup.
