Some NFL stars seem invincible—until one brutal injury changes everything. Whether it was a torn ACL, a devastating concussion, or a freak accident, these moments completely altered the trajectory of careers that were once on a Hall-of-Fame pace.
Sometimes the body never bounces back, and other times, the confidence and rhythm are lost for good. These NFL icons were never quite the same after their big injury, and the league missed out on even more legendary chapters.
19. Jamal Anderson

The Dirty Bird became a Falcons icon, but a torn ACL in 1999 ended his reign way too soon. He was never able to reclaim that Pro Bowl form again.
18. Daunte Culpepper

Before the knee injury, he was putting up video-game numbers with Randy Moss. After it? A shell of his former self bouncing between teams.
17. Ryan Shazier

One of the most heartbreaking stories in recent NFL history. His spinal injury ended a promising Steelers career and left fans wondering what could’ve been.
16. Robert Griffin III

RG3 exploded onto the scene with highlight plays and track-star speed. Then came the knee injuries, and he never regained that magic.
15. Sterling Sharpe

He was on pace to be one of the greatest receivers ever. A neck injury cut his career short just as he was hitting his prime.
14. Caleb Odom

Odom was a quiet defensive powerhouse for the Titans before injuries derailed him. The NFL quickly forgot just how dominant he once looked.
13. Cam Newton

Superman was unstoppable during his MVP year, but his body paid the price for years of punishment. Post-shoulder injury, Cam didn’t have the same juice.
12. Terrell Davis

He went from a 2,000-yard rusher to retired in the blink of an eye. Injuries zapped his explosiveness and ended a Hall-of-Fame career far too early.
11. Andrew Luck

He walked away on his terms, but it was years of injuries that pushed him there. We’ll never know just how high he could’ve soared.
10. Jordy Nelson

A torn ACL in 2015 robbed him of a step, and in the NFL, that’s everything. He had moments afterward, but the magic was mostly gone.
9. Willis McGahee

He suffered a brutal knee injury in college and still made it to the pros, but another knee issue later on stopped his momentum for good. A true what-if player.
8. Tony Romo

He could still sling it with the best of them, but the back couldn’t hold up. Once the injuries piled up, the Cowboys had to move on.
7. Bo Jackson

Maybe the biggest “what could’ve been” in sports history. One injury ruined not one, but two professional careers—those in the NFL and MLB.
6. Chris Carson

A beast of a runner with punishing physicality, Carson looked like Seattle’s future. A neck injury abruptly ended his career before age 30.
5. Sam Bradford

The talent was there, but the knees wouldn’t cooperate. Every time he got a chance, another injury set him back.
4. Michael Irvin

One of the most dominant receivers of the 90s, Irvin’s career ended suddenly with a neck injury. The Cowboys haven’t had a receiver quite like him since.
3. Carson Wentz

Wentz looked like an MVP frontrunner before his knee gave out in 2017. Since then, it’s been a carousel of teams and inconsistent performances.

2. Odell Beckham Jr.

The one-handed catch was just the beginning, but injuries slowed the lightning-fast receiver way down. His explosiveness never fully returned after the knee issues.

1. Todd Gurley

He went from Offensive Player of the Year to out of the league in a flash. Once the knee issues set in, his burst vanished, and so did his dominance.
