Ronnie Lott
It’s amazing the lengths that elite athletes go to when they want to win. Tennis star Simona Halep famously underwent a breast reduction because she didn’t want her physique to restrict her. But one former Niners star took this to the next level after he broke his finger against the Cowboys.

The bone breached his skin so Lott made an impulsive decision. He demanded that the medics cut off the tip of his finger before he returned to the field. This was in 1985 so it wasn’t even that long ago. They taped his hand and he set off after the gutsiest moment of his sporting career (via Raiders.com).
