An NFL physical is a very detailed “head‑to‑toe” medical check that teams use to decide if a player is healthy enough to sign or keep on the roster.

Big picture: what an NFL physical is

An NFL physical is basically a combination of:

  • Full medical history review
  • General internal medicine exam (heart, lungs, organs, etc.)
  • Orthopedic exam (bones, joints, past injuries)
  • Functional/strength testing
  • Lab tests and imaging (blood, urine, X‑rays, MRIs when needed)
  • Sometimes extra cardiac and neurologic testing for safety

Teams are trying to answer one question: “If we invest millions in this player, how likely is it that his body holds up?”

Core parts of the exam

1. Medical history and interview

Doctors and trainers will go deep on the player’s past:

  • Previous injuries (sprains, tears, surgeries, concussions)
  • Chronic issues (asthma, heart murmurs, high blood pressure, etc.)
  • Medications and allergies
  • Prior hospitalizations or major illnesses

At the combine or before a signing, teams may review old medical records, surgery notes, and imaging from college or previous teams.

2. Internal medical exam

This is the “regular doctor” part but more intense than a normal physical:

  • Vitals: height, weight, blood pressure, pulse, oxygen levels
  • Heart: listening for murmurs or abnormal rhythms, may add EKG or stress test if anything looks off
  • Lungs: listen for wheezes or signs of asthma or other issues
  • Abdomen: checking organs, hernias, tenderness
  • Skin: infections, rashes, healing of old scars
  • Vision and hearing screening

For some players, especially linemen or players with red flags, they’ll add deeper cardiac testing because of rare but serious risk of sudden cardiac events in athletes.

3. Orthopedic and musculoskeletal exam

This is the part most players dread, especially at the combine.

  • Full joint check: neck, shoulders, elbows, wrists, hands, spine, hips, knees, ankles, feet
  • Range of motion: how far joints move, any stiffness or instability
  • Strength testing: manual strength tests and sometimes instrumented machines to measure leg and joint strength
  • Old injuries:
    • X‑rays and MRIs of old fracture sites, repaired ligaments, or recurring problem joints
    • Stressing the joint to see how stable it really is

Doctors are looking for things like loose ligaments, arthritis, poor healing, or anything suggesting a high chance of re‑injury.

4. Neurologic checks

Because football is high‑impact, there is attention to the nervous system:

  • Concussion history and symptoms (headaches, dizziness, memory issues)
  • Basic neurologic exam: reflexes, strength, sensation, coordination, balance
  • Neck and spine evaluation, especially if there’s a history of neck or spinal injuries

If anything looks concerning, they can order advanced imaging or specialist consults.

5. Lab tests and imaging

Standard tests often include:

  • Blood work: general health, anemia, kidney and liver function, possible markers of disease
  • Urine tests: hydration, kidney issues, and league‑guided substance testing (separate, but often done in the same window)
  • Imaging:
    • X‑rays of key joints (knees, shoulders, spine)
    • MRIs or CT scans for known injuries or suspicious findings

At the combine, teams may re‑scan an old injury even if it’s years old to see how it’s holding up.

6. Genital and hernia checks

This is the classic “turn your head and cough” part:

  • Hernia exam
  • Testicular exam in males

It’s quick but important, since untreated hernias can become a real problem during a season.

How it feels from the player’s perspective

Players often describe the NFL physical (especially at the combine) as:

  • Invasive and exhausting – long lines of players going from station to station
  • Repetitive – multiple teams’ doctors may re‑examine the same joint or injury
  • High‑stakes – a small finding on an MRI can drop a player’s draft stock or void a contract

One common description from front offices: it’s like a job interview with “hundreds of eyes” on you while doctors pick apart your medical history in detail.

What can cause you to “fail” an NFL physical?

You “fail” an NFL physical if the team’s doctors decide the risk is too high for that contract or role.

Common reasons include:

  • Unstable joints (knee, shoulder, ankle) that look likely to re‑injure
  • Significant cartilage loss or early arthritis in key joints
  • Serious heart or lung issues that make playing dangerous
  • Persistent neurologic or spine problems
  • A recent major injury that has not fully healed

Different teams can reach different conclusions on the same player, so a guy might fail a physical with one team and pass with another that’s more comfortable with the risk.

Exam Area What It Includes Why It Matters
Medical history Past injuries, surgeries, illnesses, meds, concussionsReveals long-term risk and patterns of injury
Internal medicine Heart, lungs, abdomen, vision, vitals, possible EKG/stress testsDetects hidden heart, lung, or organ issues before high-level play
Orthopedic Joint stability, range of motion, strength tests, X-rays/MRIsAssesses durability and risk of re-injury in a contact sport
Neurologic Reflexes, sensation, coordination, concussion/spine reviewAddresses brain, nerve, and spine safety in collisions
Labs & urine Blood work, urine tests, hydration and organ function checksEnsures overall health and flags hidden disease or issues
Genital/hernia Hernia and testicular check in malesPrevents serious complications from untreated hernias

TL;DR

An NFL physical consists of a detailed medical history, full body exam, intensive joint and strength testing, heart and neurologic checks, lab work, and targeted imaging of current and old injuries, all designed to judge whether a player is medically safe and durable enough for pro football.
