Can an assistant referee issue a yellow card?

Answer 1

A yellow card is shown when a player is cautioned in a match.

A player or substitute receiving two cautions in the same match is sent off, which is signaled by showing the player a red card. A player that is sent off may not be replaced (i.e., his team must "play short").

Answer 2

A yellow card is given by the degree which is considered as a warning to the player for the foul he or she committed . If another foul is committed by the same player of similar degree would mean the player then might receive a red card i.e the player will be sent off and his or her team will play with a player less

Answer 3

Only the referee can caution a player or substitute. The referee will take information from the assistant to make the decision.
