College Football Redshirt Rules and the Four Game Limit

Every November the same question pops up on broadcasts and message boards: why is that freshman suddenly sitting after playing three games, and why does the coach keep saying "four" like it is a magic number? The answer is the college football redshirt rules, and they shape depth charts more than most fans realize. Here is how the rules work, where the four game limit came from, and how coaches use it every season.
I have covered enough Saturdays to know that the redshirt is one of the most misunderstood parts of the sport. It is not a punishment, it is not a medical label, and it is no longer a full year on the sideline.
What a redshirt year means in college football
Under NCAA Division I rules, a player has five years to play four seasons of competition. That five year window is often called the clock. A redshirt year is a season inside that window in which the player does not use one of his four seasons of competition. He can practice, travel, lift and attend meetings with the team. He just cannot play beyond a set limit without burning the season.
The term comes from an old story about a Nebraska player in the 1930s who practiced in a red jersey without playing, but the modern meaning is purely about eligibility. Most programs redshirt a large share of each freshman class, especially linemen who need a year or two in the weight room before they can hold up against 300 pound opponents.
The four game rule explained
Before 2018, a player who appeared in even one game lost his redshirt for that season, unless he qualified for a medical hardship. In June 2018 the NCAA changed that. Since the 2018 season, a Division I football player can appear in up to four games in a season and still keep the year as a redshirt.
- Four games, any four. They can be early, late, or spread out across the schedule.
- Postseason counts. Conference championship games, bowl games and playoff games all count toward the four.
- Any snap counts. One special teams play on a punt counts as an appearance, the same as a full game at quarterback.
- Game five ends it. Step on the field in a fifth game and the season counts as one of your four.
That last point is why coaches track appearances so carefully in November. A freshman who has already played four regular season games may sit out a rivalry game so he can still play in the bowl without losing the year. Our guide to bowl eligibility rules explains how teams qualify for those extra games, which matter here because they eat into the same four game budget.
The 2020 exception
Because of the pandemic, the NCAA ruled that the 2020 season did not count against any player's eligibility. That is why you saw so many sixth year and even seventh year players on rosters through the mid 2020s. Those players have now largely cycled out, and rosters look closer to normal again.
How coaches use the redshirt every season
The four game rule turned the redshirt from a yes or no decision into a planning tool. A typical approach for a top program looks like this.
- Weeks 1 to 4: freshmen get special teams snaps or garbage time in nonconference blowouts.
- Midseason: coaches hold appearances back so injured starters can be replaced without burning a year.
- November: staff decide which freshmen are ready to play every week and let them pass four games on purpose.
- Bowl season: remaining redshirt freshmen often play the bowl game, which gives them real snaps and a preview of next year.
The rule has also helped teams with depth. Before 2018, a coach facing a run of injuries in October had to choose between playing a thin depth chart or burning a full season for a freshman who might only play twice. Now that freshman can fill in for a few games with no eligibility cost.
The redshirt and the transfer portal
The four game rule had a side effect that few people predicted. Veterans who lose their starting job can play up to four games, then sit, keep the season as a redshirt, and transfer with an extra year intact. Clemson quarterback Kelly Bryant did this in 2018 after losing his job to Trevor Lawrence, and Houston quarterback D'Eriq King did the same in 2019.
Combined with looser transfer rules, that move is now common. It is one reason the portal has changed how programs recruit, a shift we covered in how the transfer portal reshaped college football recruiting strategy. When a senior starter suddenly vanishes from the depth chart after week four, this is usually why.
Why redshirting every freshman is not always smart
Fans often assume a redshirt is always the smart, patient choice. I think that view is outdated. When players could not easily transfer, saving a year meant keeping a player in your program for five seasons. Today, a talented freshman who spends a year on the scout team may decide he has better chances elsewhere and leave before that extra year ever pays off.
The money side matters too. With players now earning name, image and likeness income, playing time affects what a player can earn. A freshman cornerback who could contribute in nickel packages may be better served, and more likely to stay, if he plays 12 games instead of four. Many coaches now redshirt linemen and raw athletes, while playing skill players who are ready.
The rules themselves have also been under review. The NCAA has debated replacing the five year clock with a simpler model of five seasons of competition, which would make the redshirt far less important. Check the current rule for the season you are watching, because eligibility policy has been changing faster than at any point in decades.
Medical redshirts and hardship waivers
A medical hardship waiver is different from a standard redshirt. It applies when a player suffers a season ending injury or illness. In football, the injury must happen before the second half of the season, and the player must not have appeared in more than three games or 30 percent of the team's scheduled games, whichever is greater. The school applies to its conference office, which reviews medical records.
Because the four game rule covers most of those cases already, hardship waivers matter most for players who were hurt after playing in a few games and then could not return. A player can also use a hardship year in addition to a normal redshirt, as long as both fit inside the eligibility rules.
Frequently asked questions
How many games can you play and still redshirt in college football?
A Division I football player can play in up to four games in a season and still keep it as a redshirt year. Postseason games count toward that limit. Appearing in a fifth game uses one of the player's four seasons of competition.
Does a bowl game count toward the redshirt limit?
Yes. Bowl games, conference championship games and playoff games all count as appearances. That is why coaches often hold freshmen out of late regular season games so they can play in the bowl without losing the year.
What is the difference between a redshirt and a medical redshirt?
A standard redshirt is a planned choice to keep a season of eligibility, using the four game limit. A medical redshirt, or hardship waiver, is granted after a season ending injury or illness early in the year, and it requires approval from the conference. Both preserve a season, but the medical version depends on documentation and timing.
