In soccer/football, the indicator that a certain player is to leave the field and may not be replaced for the course of a match. Red cards are given out for flagrant fouls, generally with intent to injure an opposing player, for an intentional hand ball to prevent a goal, or for receiving two yellow cards.*

*In some low-level leagues, like the Virginia High School League, a "two-yellow replace" rule is used. This means that a player receiving a red card automatically as a result of incurring two yellows may be replaced.
