A “medical redshirt” is the informal name for what the NCAA calls a hardship waiver: a way for a player who loses most of a season to injury or illness to get that season of eligibility back. It’s distinct from a standard redshirt — which a player earns by choice by staying under four games — because it applies after the fact, to a season the player intended to play but couldn’t. If granted, the season doesn’t count against his four, even if he played more than four games before getting hurt.
The rule exists because injuries are random and the four-seasons-in-five-years framework is rigid. Without it, a starter who tore an ACL in Week 6 would lose a full season of eligibility for six games. With it, he can get that year back — but only if he meets specific thresholds on when the injury happened and how much he’d played, and only if the school submits documentation and the conference or NCAA approves it.
The chart below covers the requirements, the process, and how it compares to a standard redshirt. Take a look, then we’ll get into the cases that get denied.

The requirements
What a player must meet
| Requirement | Standard |
|---|
| Timing of the injury | Must occur before the completion of the first half of the season (the midpoint of the team’s scheduled regular-season games) |
| Games played | The player must have competed in 30% or fewer of the team’s scheduled games (including postseason) — for a 12-game season, that’s 3 games; 4 games rounds up under the 2024 adjustment |
| Season-ending | The injury or illness must be incapacitating for the rest of the season — the player cannot return |
| Documentation | Contemporaneous medical records from the team physician or treating doctor establishing the injury and its date |
| Who decides | The player’s conference office (for conference members) or the NCAA; the school files on the player’s behalf |
| Timing of the request | Typically filed after the season; must be granted before the player competes in what would be his final season |
Thresholds per NCAA Bylaw 12.8.4; the 30% calculation includes postseason games.
Medical vs. standard redshirt
Two ways to keep a season
| Standard redshirt | Medical hardship waiver |
|---|
| How it happens | By choice — player is held to 4 or fewer games | By circumstance — season-ending injury or illness |
| Game limit | 4 games | 30% of scheduled games (roughly 3-4), injury before midseason |
| Approval needed | None — automatic if under 4 games | Yes — conference or NCAA waiver |
| Can be combined? | Yes — a player can have a standard redshirt and a medical hardship in different seasons | Yes |
| Effect | Season doesn’t count | Season doesn’t count |
| Common name | Redshirt | Medical redshirt |
Common scenarios
What gets approved and what doesn’t
| Scenario | Likely outcome |
|---|
| ACL tear in Game 3 of a 12-game season, out for the year | Approved — before midpoint, under 30% |
| Broken foot in Game 5, out for the year | Denied — 5 games exceeds the 30% threshold (unless a rounding exception applies) |
| Concussion in Game 2, cleared and played Game 10 | Denied — the injury wasn’t season-ending |
| Injured in Game 7 (past midpoint), out for the year | Denied — after the first half of the season; the player would need a separate hardship/legal waiver |
| Injured in preseason camp, never played | No waiver needed — the player simply redshirts (0 games) |
| Injured in Game 3, then played in the bowl game | Denied — competing later in the season disqualifies the request |
MEDICAL REDSHIRT FACTS
It’s granted, not claimed
Unlike a standard redshirt, a school must apply and prove the case; most are approved, but the timing and 30% rules are strict.
Not just for injuries
Illness, surgery, and documented mental-health conditions can qualify under the same hardship framework.
The 6th-year waiver is different
A player who needs a sixth year (beyond the 5-year clock) files a separate extension waiver, which requires losing two seasons to circumstances beyond his control.
Why Cases Get Denied
The two thresholds do most of the rejecting. A player hurt in the second half of the season doesn’t qualify no matter how serious the injury, because the rule assumes he got meaningful value from the year. And a player who exceeded the 30% game limit — typically four-plus games in a 12-game season — is over the line even if he was hurt in his fourth game. The ‘season-ending’ requirement catches the rest: any return to competition, including a bowl game, ends the claim. Players who fall just outside these lines can still pursue a general hardship or extension waiver, but those are case-by-case and less often granted.
The Bottom Line
A medical redshirt is an NCAA hardship waiver that gives back a season lost to injury or illness — provided the injury came before the season’s midpoint, the player appeared in 30% or fewer of the team’s games, and he never returned that year. It’s the injury-triggered counterpart to the standard four-game redshirt, and it can be combined with one.
