Donovan McNabb
Anybody who broke their ankle will know that it’s agonizing to put their weight on it. Now imagine playing an NFL game against some of the biggest athletes on the planet. That’s exactly what McNabb did in the gutsiest performance of his career in 2002. He rejected medical concerns over his foot after an injury during a game against Arizona.

McNabb refused to undergo an X-ray and went back into the fray. Amazingly, the QB had one of his greatest games with a broken ankle. He completed 20 of 25 pass attempts for four touchdowns. Perhaps the acute pain sharpened his mind and forced him to make everything count. Whatever happened, it was an outstanding day for the Eagles star (via Bleacher Report).
