S1E6 Refs and Discipline: Yellow Cards, Red Cards, Free Kicks, Penalties, and More


Everything you need to know about how soccer punishes rule-breakers and the people calling fouls
If you’ve ever watched a soccer match and wondered why a referee whipped a brightly colored card out of their pocket, you’re not alone. On this episode of Soccer Explained, we break down sanctions (the official term for the discipline players receive for breaking rules) and the officials who keep the game running. This post covers the highlights, but the episode also has stories, tangents, and the origin story of perhaps Soccer’s greatest heel. Give it a listen!
Yellow Cards and Red Cards
Not every foul gets an official sanction. Sometimes the ref gives a verbal warning first, which is informal. It doesn’t have real consequences for discipline, unlike, say, a baseball ump signaling to the dugout. But when things escalate, out come the cards. Refs carry actual physical cards in their pockets that they flash at players to indicate they’re giving out a sanction. A yellow card is an official caution, also called a “booking” because the ref writes the player’s name and the details of their foul in a little notebook. Two yellows in one game and the player is sent off, meaning their team plays the rest of the match a player down. A red card is an immediate ejection with the same consequence.
How bad is playing down a player? Imagine a power play in hockey that lasts the entire game. It completely transforms the match.
Coaches and staff can get carded too, and a red card usually means sitting out the next game or more in that league or tournament, even if the suspension has to carry over to a future season or competition.
How Play Restarts After a Foul
When a foul happens, play usually stops, with one big exception: the advantage rule. If the fouled team actually benefits from play continuing, the ref lets it go. Think of it like declining a penalty in football, except the ref makes the call instead of the coaches. They signal it by extending their arms so everyone knows the foul was seen, and they wait for the next stoppage in play to hand out any sanctions.
The most common restart is an indirect free kick, where the fouled team gets to restart play with the ball where the foul happened, but can’t shoot directly at the goal. Two players on their team have to touch the ball before a shot. Defenders have to stand at least 10 yards away from the ball until play resumes, unless the kicking team opts for a quick restart and the defenders didn’t have time to take their position.
A direct free kick is the same, but you can shoot right away. Near the penalty area, these become dangerous scoring chances. When defenders line up to block the shot, that’s called a “wall,” and players on the offensive team have to be a yard away from the wall before the kick happens.
If a foul that would require a direct free kick happens inside the penalty area, the result is a penalty kick: a shot from 12 yards out with only the keeper in the way. The keeper has to have one foot on or behind the goal line until the kicker strikes the ball. The odds heavily favor the kicker, making it one of the most serious consequences in the game.
How Refs Choose Sanctions
Refs often have a lot of discretion in deciding which sanctions to give out. Overall, the harshest sanctions go to fouls that are intentional, repeated, dangerous to player safety, or that constitute the “denial of an obvious goal-scoring opportunity” (abbreviated DOGSO, pronounced “dog-zo”).
Who Are All These Referees?
The Referee is the official title for the main authority on the field, calling fouls, issuing sanctions, keeping time, deciding whether goals count, and more. You’ll also hear them called “head referee” “center ref,” or other variations. Two Assistant Referees (Ars, or “linesmen”) run the touchlines throwing flags to signal they think the referee should make offside, out-of-bounds, or other calls. The fourth official stands near the benches, managing substitutions and other administrative tasks, and holding up the board showing the minimum stoppage time the center ref has decided to add.
The Video Assistant Referee (VAR) is a more recent addition. Sitting in a video room off the field, the VAR can recommend that the center ref review a play on a pitch-side monitor. Players and coaches cannot challenge calls. Reviews are limited to offenses in the moments leading up to goals, whether goals count, penalty kick decisions, red cards (not two yellows, just reds), and questions of whether fouls were given to the wrong player.
Not every professional league has VAR, but the World Cup and MLS both do. For leagues that don’t, there are Additional Assistant Referees, called AARs or goal line refs, who stand near the goals to monitor what VARs cover.
The Human Element
One thing we emphasized on the show is how much subjectivity is built into soccer officiating. Some calls are fairly black-and-white, like offside or handball. But for many fouls, the ref has enormous discretion. What fans and commentators usually care most about is consistency. In the early minutes of a match, the referee sets the tone for how strict or lenient they’ll be, and the players adjust. It’s a constant negotiation in a way that can feel different from many American sports.
