what does retired hurt meaning in cricket

In cricket, a batsman may retire from an innings at any time when the ball is dead; they must then be replaced by a teammate who has not been dismissed). There are two types of retirement in cricket: retired hurt and retired out. A batter is considered retired hurt if they are unable to continue their innings because of illness, injury, or any other unavoidable cause, and they must consult with on-field umpires before being granted permission to withdraw from their innings. If a batter retires hurt, they are entitled to resume their innings if they recover before their teams innings end, but they can only resume their innings at the fall of a wicket or the retirement of another batter in their respective team. If a batter retires for any other reason or without the umpires permission, they are considered retired out and may not return to the innings unless the opposing captain offers an exemption). Retired out is a tactical substitution wherein a batting side can replace a batter if they feel someone can do a better job for the team, keeping the game situation in mind. The runs scored by a retired hurt batter will be added to their career total as well as the innings, and they will be considered not out for statistical purposes when calculating a batting average.
