Vice-captain
The captain may be assisted by a vice-captain. This is particularly useful when the captain is forced to leave the field of play during fielding, due to injury or illness (etc.). Some teams also allocate the vice-captain a more or less formal role in assisting with team selection, discipline, field-setting etc. There is no such rule that a vice captain will be appointed as the next captain.
Vice captain may have a say in setting up the batting order along with the captain in consensus seeing the team's capability.
When a limited-overs match is affected by rain or bad light, and the Duckworth Lewis method is used to adjust the target for a team batting second, because of the complexity of the situation, the fielding side's captain may decide to give a piece of paper with the Duckworth Lewis calculations to the vice captain or another player, so that he is not overburdened with duties.
