what is meant by retired hurt in cricket

In cricket, a batsman may retire from an innings at any time when the ball is dead, and they must then be replaced by a teammate who has not been dismissed). If a batting player becomes injured or falls ill, or some other exceptional circumstance forces them to leave the field, and they receive permission from the umpire, they may retire not out. This situation is officially recorded on the scorecard as "retired - not out," though the unofficial term "retired - hurt" is often used on broadcasts instead. The batsman is considered not out for statistical purposes, such as when calculating a batting average). If the retired batsman recovers before the end of the innings, they may resume batting, upon the dismissal or retirement of another batsman. If they cannot return to batting by the end of the innings, they are considered to have retired out). Therefore, the key difference between retired hurt and retired out is that a retired hurt batsman is allowed to resume batting if they recover before the end of the innings, while a retired out batsman cannot resume batting.
